Unable to obtain process output within 15 seconds

[SpinDreams]

I'm recently getting the following reported for PS output in the high 5 minute load emails from at least 2 of my servers.

"Unable to obtain process output within 15 seconds - Timed out"

If I run PS from shell it reports fine.

Any ideas why?

Same pb here

csf v6.38

May be it is a BUG

We have the same problem on 2 servers. The message is consistent no matter when the notice is sent or how high the load. Can't say which version it started with but we keep looking for the fix. It's difficult to diagnose the load issue without the process list.

We have been receiving loadalerts, though the processlists receive the following.

Output from ps:
Unable to obtain process output within 15 seconds - Timed out

Additionally, the other two files only provide one line of output, which does not help much for diagnosing the issue. Is this a known issue, or are there any workarounds that are available?

We've identified the problem and will have a fix for it in the next release. In the meantime you can modify the latest /etc/csf/lfd.pl and change line 2566 from:

Code: Select all

				@proclist = &syscoammnd(__LINE__,$config{PS},"axuf");

to:

Code: Select all

				@proclist = &syscommand(__LINE__,$config{PS},"axuf");

then restart lfd.

This is now fixed in csf v6.42:
