Re: [X2Go-User] Long-running x2goagent, high memory usage
Yeah, I could absolutely compile my own version. I think it might be better to try with the .deb packages you linked first though. I need to ask my users for a window where I can shut down everything first, so might take a few days before I can organize this. — Johannes Töger Associate Senior Lecturer Cardiac MR Group Department of Clinical Sciences Lund, Clinical Physiology Lund University, Sweden -Original Message- From: Ulrich Sibiller Sent: Thursday, January 23, 2020 19:43 To: Johannes Töger Cc: Bernd Schubert ; x2go-user@lists.x2go.org Subject: Re: [X2Go-User] Long-running x2goagent, high memory usage On Thu, Jan 23, 2020 at 7:35 PM Johannes Töger wrote: > > Thanks to you both for getting involved in this. > > I've been swamped with other things, so not much to report.

Thanks to you both for getting involved in this. I've been swamped with other things, so not much to report. I did manage to plot the x2goagent memory use over time though. Maybe this can help. Link to plot: https://imgur.com/a/lDqZ2zd As you see, several users have a constant memory use. However, 3 of them have a constantly increasing memory use. So not isolated incidents that leak, but rather a continuous drip. — Johannes Töger Associate Senior Lecturer Cardiac MR Group Department of Clinical Sciences Lund, Clinical Physiology Lund University, Sweden -Original Message- From: x2go-user On Behalf Of Bernd Schubert Sent: Thursday, January 23, 2020 16:11 To: Ulrich Sibiller Cc: x2go-user@lists.x2go.org Subject: Re: [X2Go-User] Long-running x2goagent, high memory usage On 1/23/20 3:41 PM, Ulrich Sibiller wrote: > Ok, that's fine, too!

I had similar issues in the past with x2go, but right now long running sessions work pretty well. I'm also coding all the time and the compiler sanitizers are great help and work so much faster than valgrind - I just tried to point that out.

Re: [X2Go-User] Long-running x2goagent, high memory usage
Just a little update: I have tried to integrate valgrind into the x2go setup but I failed. I'll try again... In your initial bug report you showed some measurement where you accumulated the memory per user. Can you verify that this amount is is tied to x2goagent processes?
