[Freeipa-users] Antwort: Re: Antwort: clean-run doesn't work

[Alexander Frolushkin]

Hello.
We have 19 RHEL 7.1 IPA (ipa-server-4.1.0-18.el7_1.3.x86_64) servers.
Debug level was changed this way on 4 of them:
dn: cn=config
changetype: modify
replace: nsslapd-errorlog-level
nsslapd-errorlog-level:24576
-
replace: nsslapd-accesslog-level
nsslapd-accesslog-level:256
EOF

After this, IO was increased significally.
Two of servers hangs after some time, a lot of dups appears on most IPA servers in domain.


WBR,

Fascinating.

Can you Red Hat guys reproduce this in you test environment?

Most of my tests are on RHEV with RHEL 7.1, I have not seen a crash of DS.
About the test case, you installed a server+replicas (version ?), then turn on errorlog-level (do you remember what level).
That would slow down the DS instance and fill errors log.
Then you hit extremely frequently a crash. Do you remember what kind of the load search/mod/add/del ?

thanks

Thanks,

Hello everyone.
I can confirm this on VMWare, recently we have the similar issue when enabled dirsrv debug on 4 of our 19 IPA servers :(

yes... we has had a really often a crash on virtual machines installations. On bare metal we had 2-3x a crash.

That was the reason for us to destroy all IPA VM's. There seems to be an IO issue on VM's with IPA (rhev virtualisation here). You can see it extremly if you turn the debug level higher.
