    Betreff: [X2Go-Dev] x2gocleansessions not handling sigchld
         An: x2go-dev at lists.berlios.de

Hello,

Running x2go 3.1.1.4-0~592~precise1 on 12.04, I'm still seeing
x2gocleansessions not properly cleaning up after its children, resulting
in a bunch of zombie processes.

I added a very basic SIGCHLD handler to the perl script and it seems to
have been doing the trick, at least for the past few hours.

I just added:
$SIG{CHLD} = sub { wait };

After the existing:
$SIG{TERM}=\&catch_term;
