Having slow Ubuntu 11.04?

I am using Ubuntu 11.04 as a VM hosted on a Windows machine. I suspend the Ubuntu VM most of the times to resume my work later. Of late, I observed that VM was performing very slow. I checked the CPU consumption behavior and found that a process “telepathy-logger” was using 100% of CPU!

After digging more, I found that this was a daemon process and used by Empathy messenger. In fact this is a known bug in “telepathy-logger” that if a machine resumes, this daemon misbehaves and consumes up to 100% CPU. Link.

Solution:

  • Kill the daemon [   $killall telepathy-logger   ]
  • Do not use Empathy messenger if you plan to resume a suspended workstation
