Package: x2goserver
Severity: normal

I am running x2goserver 4.0.1.9 on an EdgeRouter Lite
with a dual core 500 MHz dual Octeon CPU.

I looked at the CPU time consumption while no x2go session was active.

ps -A shows the following processes.
  609 ?        00:00:02 x2gocleansessio
11923 ?        00:00:01 x2golistsession
11930 ?        00:00:01 x2gosqlitewrapp

609 is the parent 11923, 11930 are children with varying PID.

These 3 processes are shown in program top often as major CPU consumers.

After 4700 s uptime x2gocleansession has used

2041 s CPU time spent in user code, including time from children
 538 s CPU time spent in kernel code, including time from children

Why is x2golistsession eating up 25% of the available CPU?

Best regards

Heinrich Schuchardt
