When I execute ps on the server runs ubuntu 12.04, it always freeze.

like this:

root@xxx:xxxxx# ps

  PID TTY          TIME CMD

26328 pts/1    00:00:00 sudo

26329 pts/1    00:00:00 su

26330 pts/1    00:00:00 bash

Signal 11 (SEGV) caught by ps (procps version 3.2.8)

Please send bug reports

And, this makes high load average as standing process.

This error have never happens until I add many users that I must add.

I searched on google many times, but I can't find how to fix it.

Could you tell me the solution?

Sorry for my dirty English.

P.S.:

I run this machine on vmware esxi 5.1.

And, It is created by Ubuntu 12.04 "Precise Pangolin" Minimal CD.
