[Spacewalk-list] remote command responses are really slow

[P.Cookson at bham.ac.uk]

Hi

This MAY be due to a similar issue someone has reported with systems going offline. Are you using OSAD? If so, my personal notes, below, may help to identify your problem. If everything has been done correctly it may be an infrastructure problem though ie un-reliable network connection or NTP?

By default, the rhnsd daemon on a client system connects to the Spacewalk server every four hours (see /etc/sysconfig/rhn/rhnsd) and performs any updates or actions that have been scheduled. If you install the OSA daemon, you can apply updates and actions to client systems immediately from the Spacewalk server.

osa-dispatcher
Server-side service that determines when an osad client instance needs to be pinged or run rhn_check and sends a message telling them to do so. This is installed when Spacewalk is installed.

Open Source Architecture Daemon (OSAD)
Client-side service that responds to pings and runs rhn_check when told to by osa-dispatcher.

See official documentation, at the following link, for more details:

https://github.com/spacewalkproject/spacewalk/wiki/OSADSetup

Install OSAD and related RHN/Spacewalk packages
# yum -y install osad rhncfg rhncfg-actions rhncfg-client

Spacewalk Actions Control - Enable Scheduled Actions
# rhn-actions-control --enable-all

Spacewalk Actions Control - Show Status
# rhn-actions-control --report

Start OSAD
# systemctl start osad.service OR service osad start

Enable OSAD
# systemctl enable osad.service OR chkconfig osad on

OSAD Log File
/var/log/osad

Phil

Subject: [Spacewalk-list] remote command responses are really slow

We previously ran Spacewalk 2.4 and early on, we were able to run remote commands to our registered servers and they pretty much responded right away.  After a while we got to the point where almost none of the servers would respond to remote commands.  We now have spacewalk 2.7 running and I'm trying remote commands again, and they are still extremely slow to respond.  Just a simple command like hostname, sent out to 60 servers.  Only 12 responses so far after 30 minutes, the rest haven't failed they are still trying.  Any idea what would cause this slowdown or how to correct it?  We have a total of 430 servers registered in our environment.
