[X2go-dev] X2go-dev Digest, Vol 20, Issue 11

If its just the size of the file that's a problem can you possibly just
quota the log file's size?

Manage Log File size on
Ubuntu<http://www.watchingthenet.com/how-to-manage-log-file-size-archive-deletion.html>is
one writeup which gives a lot of detail on how to use LogRotate.

I think this is the Man page for
LogRotate<http://linuxcommand.org/man_pages/logrotate8.html>
.

If you are just trying to figure out how to reduce the number of messages
the above won't help.
