[Freeipa-users] clients very slow

[David Fitzgerald]

Hello Everyone,

I work at a small university and I deployed freeIPA on my Linux network over the summer break with no (known) problems,  and everything worked as expected.  However, now that the semester has started and the Linux system is under a much higher load, I am noticing that my client machines will randomly slow to a crawl.  For example, I have a lab of 25 machines.  The students can log in ok, but after a time, a few of the machines will freeze so that the users on those machines cannot do anything.  After a few minutes, the frozen machines will unfreeze, but other machines will freeze up.  I can't see any pattern to what machines freeze up.  I did not have this problem when running NIS, so I suspect it is something in freeIPA but I am not sure what to look for to solve the problem.  Probably a setting somewhere needs tweaked but I don't know.  The server and clients all run Scientific Linux 6.2.

Can anyone help me troubleshoot this?

Thanks!

Dave
