The O/S of the m/c. is RHEL AS 3.0 with kernel 2.4.21-20. with x86_64 and taroon update 3. The RAM is 2GB with swap memory another 2GB. The server is functioning as mail server and this is the only application which is loaded onto the system with a third party vendor's mail application package. For quite some time the swappable memory itself was found to be consumed rather exhausted to its full quota of 2GB by the application resulting in no free memory for subsequents tasks to execute. As a result of this not only the application but also the system itself becomes frozen/hangs. The system becomes inaccessible even through remote machines using rlogin or putty etc to revive.

There may be too many processes spawned by the application which are running in the background. Hence thery are consuming too much memory. Try using "ps -ef" to see running processes. Consult the manual for the application to see if threre is any option to limit the number of processes, or any option to limit the memory usage. We use the option 'default_process_limit' in Postfix to limit the number of processes of the mail server. Also check the man pages of setrlimit, limit and ulimit. regards Sultan ----- Original Message ----- From: Mahalingam Subramaniam To: redhat-sysadmin-list at redhat.com Sent: Friday, February 02, 2007 10:01 AM Subject: to recover the swap memory Dear All I shall greatly appreciate and honour, if anyone can suggest the solution to the below mentioned issue.

Is this a good > idea? This is sort of a hack, but Linux allows you to create and mount ramdisks. These are regions of memory that you allocate and tell the kernel to treat like a disk device. So if you _really_ want things on disk in memory, you can create a ramdisk, copy the files to the ramdisk, and then tell the application that the data is located at wherever you mounted the ramdisk. I need to emphasize that this is really a hack. If you need to be able to write data, then you will definitely need some mechanism that synchronizes writes to the ramdisk with the contents on disk -- otherwise when the server loses power unexpectedly, all of the data that was "written" will be lost. On the other hand, if you have some read-only data this is probably a fine solution. If the Basic system makes use of the mmap() call, this kind of thing may actually be happening behind the scenes already, with the kernel buffering disk reads and writes in memory. I think that the kernel is capable of buffering some other kinds of kids reads and writes in memory as well, so this may not even be an issue. -- Evan Klitzke From hjnmolly at hetnet.nl Tue Feb 6 10:02:25 2007 From: hjnmolly at hetnet.nl (harold molly) Date: Tue, 06 Feb 2007 11:02:25 +0100 Subject: Fastest System Possible In-Reply-To: <03f801c7494f$1edaac80$09000032@bill> References: <03f801c7494f$1edaac80$09000032@bill> Message-ID: Question Depends on the characteristics of usage(application) are there many reads,writes,calculations ? is your network stack optimized, for service requests? consider tuning your filesystem.

At anyrate, syncing with ntp will not update his system to the new timezone rules for the US. So what will do that. Download the latest tzdata package which has the fix in it. I forget the exact version, but the latest one for RHEL 4 should do.

Any ideas? You might have a negative passwd or group entry cached via nscd. You can invalidate the lookup cache by doing "nscd -i passwd" followed by "nscd -i group". Then do getent passwd $username and see if the lookup succeeds. -- Matthew Galgoci GIS Production Operations Red Hat, Inc 919.754.3700 x44155 From Christopher.Angel at lightsource.ca Thu Feb 8 16:11:48 2007 From: Christopher.Angel at lightsource.ca (Christopher Angel) Date: Thu, 8 Feb 2007 10:11:48 -0600 Subject: NIS Setup Issue In-Reply-To: References: <19446BD55BAD0140BDA719E4E7D8EF82025D325D@srv-mail-01.clsi.ca> Message-ID: <19446BD55BAD0140BDA719E4E7D8EF82025D32B9@srv-mail-01.clsi.ca> > > You might have a negative passwd or group entry cached via > nscd.

Is the user credential system used by the cifs server active directory-like? You might be able to do something where you grab a kerberos ticket from the user at login, authed against the AD server, which is then used to provide the user credentials for the samba/cifs mount? I'm talking entirely theoretically here, I've never messed with active directory. It's crazy enough that it might end up being workable though. -- Matthew Galgoci GIS Production Operations Red Hat, Inc 919.754.3700 x44155 From Art.Wildman at noaa.gov Wed Feb 21 17:07:56 2007 From: Art.Wildman at noaa.gov (Art Wildman) Date: Wed, 21 Feb 2007 12:07:56 -0500 Subject: RHEL v4 can't find HDD issue In-Reply-To: <1d0043e80702150745s70c57ad3l1373b300b5277096@mail.gmail.com> References: <1d0043e80702150745s70c57ad3l1373b300b5277096@mail.gmail.com> Message-ID: <45DC7C6C.80909@noaa.gov> Serial ATA (SATA) Linux hardware/driver status report http://linux-ata.org/driver-status.html http://www.google.com/search?q=Linux+SATA+ICH8 2.

Hardware does not support hotplug. "Warmplug" support is possible. Update: ICH6/7/8 include support for addressing the SATA PHY registers.

Update: Boot-time, probe-time issues continue to persist in some cases, related to the "PCS" register. The ata_piix driver in 2.6.18 and later provides a "force_pcs" module option to help users deal with this (values: 0=default, 1=ignore PCS, 2=honor PCS).

RHEL5b2 works just peachy in native SATA mode, as does using RHEL4 with a supported PCI SATA card instead of the onboard chipset. -- William Anderson, Systems Administrator Concept Systems Ltd. | +44 (0)131 200 4789 wanderso at csl.co.uk | http://www.csl.co.uk/ This email and any files transmitted with it are confidential and are intended solely for the use of the individual or entity to whom they are addressed.

Mapping & mounting the %HOMESHARE% is usually done via smb.conf, winbind, and your logon.bat script stored in a 'netlogin' location, depending on your samba server type, auth mechanism and domain architecture. @echo off rem # logon.bat - NT/SMB logon script rem # use DOS-formatted text (CR/LF CTRL-V, CTRL-M) echo Executing Samba Logon Script echo "" rem ...... Reset the current time to the Samba server rem .... 'time server = yes' is required in /etc/smb.conf echo Setting Current Time... net time \\SMBSERVER /set /yes echo Mapping Users "home" directory net use H: \\SMBSERVER \home\%U% If you login to a Samba Member Server, PDC or WindowsAD Domain, $HOME is automatically mounted (once authenticated) for that user if defined in your smb.conf, winbind settings & configured in your logon script. You don't want to auth users (bad idea)? You may have to map the share in a login script... but, the $HOME share is a built-in feature of samba servers and can be mounted via 'smbmount' commands. http://samba.org/samba/docs/man/Samba-HOWTO-Collection/FastStart.html #============================ Share Definitions ============================== [homes] comment = Home Directories valid users = %S browseable = no writeable = yes # Un-comment the following and create the netlogon directory for Domain Logons ; [netlogon] ; comment = Network Logon Service ; path = /home/netlogon ; guest ok = yes ; writable = no ; share modes = no # Un-comment the following to provide a specific roving profile share # the default is to use the user's home directory ;[Profiles] ; path = /home/profiles ; browseable = no ; guest ok = yes #======= Some global samba server settings are important for this to work [Example of Samba Domain Member Server]... http://samba.org/samba/docs/man/Samba-HOWTO-Collection/FastStart.html#fast-member-server http://www.samba.org/samba/docs/man/Samba-HOWTO-Collection/ServerType.html For Auto-mounting smb shares on Linux clients, a rather ugly hack exists here...
