Description of problem: I'm running x2goclient at home connecting to x2goserver at work via an ssh connection. Everything works fine until I log out of my session at work. The main window where I was talking to work goes away, but the x2goclient window stays around and cpu usage goes to 100% as it never terminates. Sometimes the "power" button won't work either to kill the session. Version-Release number of selected component (if applicable): x2goclient-4.0.5.0-3.fc23.x86_64 How reproducible: It is random, sometimes (probably more than 50%) it terminates normally, other times it does the 100% cpu thing and never goes away without me hitting it with a big stick. Steps to Reproduce: 1.see above 2. 3. Actual results: randomly hangs at 100% cpu Expected results: terminates normally every time Additional info: Sometimes I get the impression that it is more likely to hang if I've iconified the initial client window, but it is so random, it is hard to tell if this is a legit observation.
Can you please test https://bodhi.fedoraproject.org/updates/x2goclient-4.0.5.1-1.fc23
Well, I've installed it and it seems to work, but I'm not sure if I'll be able to decide it fixes the hang since it is so random :-). If it does hang again, I'll certainly record that here.
I've been using the x2goclient-4.0.5.1-1.fc23.x86_64 pretty regularly, and still haven't seen it go into an infinite loop. Maybe it does fix the problem.
Let's hope it is then. Feel free to reopen this bug if you see it again.
It finally went into an infinite loop again when I logged out of the remote session (but it sure seems much much less likely than it was before because I have used it quite a lot without seeing the problem again till just now). For what it is worth, I ran an strace on the infinite looping program and I see this stuff repeated over and over: recvmsg(7, 0x7ffd108fd890, 0) = -1 EAGAIN (Resource temporarily unavailable) recvmsg(7, 0x7ffd108fd870, 0) = -1 EAGAIN (Resource temporarily unavailable) poll([{fd=4, events=POLLIN}, {fd=7, events=POLLIN}], 2, 0) = 0 (Timeout) recvmsg(7, 0x7ffd108fd890, 0) = -1 EAGAIN (Resource temporarily unavailable) recvmsg(7, 0x7ffd108fd870, 0) = -1 EAGAIN (Resource temporarily unavailable) poll([{fd=4, events=POLLIN}, {fd=7, events=POLLIN}], 2, 0) = 0 (Timeout) ... I am changing the status back to NEW.
This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '23'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 23 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
I still see this sometimes, it isn't as common as it once was.

I've run x2go from my fedora 26 desktop at work to my fedora 24 system at home and the fedora 26 x2goclient seems to always go into an infinite loop when I log out of the fedora 24 session by closing the last app which the .xinitrc file was waiting for. An strace of the fedora 26 x2goclient infinite loop shows this stuff over and over: recvmsg(6, {msg_namelen=0}, 0) = -1 EAGAIN (Resource temporarily unavailable) recvmsg(6, {msg_namelen=0}, 0) = -1 EAGAIN (Resource temporarily unavailable) poll([{fd=3, events=POLLIN}, {fd=6, events=POLLIN}, {fd=7, events=POLLIN}, {fd=20, events=POLLIN}, {fd=25, events=POLLIN}, {fd=29, events=POLLIN}], 6, 0) = 0 (Timeout) recvmsg(6, {msg_namelen=0}, 0) = -1 EAGAIN (Resource temporarily unavailable) recvmsg(6, {msg_namelen=0}, 0) = -1 EAGAIN (Resource temporarily unavailable) poll([{fd=3, events=POLLIN}, {fd=6, events=POLLIN}, {fd=7, events=POLLIN}, {fd=20, events=POLLIN}, {fd=25, events=POLLIN}, {fd=29, events=POLLIN}], 6, 0) = 0 (Timeout) recvmsg(6, {msg_namelen=0}, 0) = -1 EAGAIN (Resource temporarily unavailable) recvmsg(6, {msg_namelen=0}, 0) = -1 EAGAIN (Resource temporarily unavailable) The /proc/pid/fd directory of this looping program looks like: lr-x------ 1 tweety tweety 64 Jul 31 10:46 0 -> /dev/null l-wx------ 1 tweety tweety 64 Jul 31 10:46 1 -> /dev/null lrwx------ 1 tweety tweety 64 Jul 31 10:46 10 -> socket:[104619] lr-x------ 1 tweety tweety 64 Jul 31 10:46 11 -> /dev/urandom lrwx------ 1 tweety tweety 64 Jul 31 10:46 12 -> socket:[103698] lrwx------ 1 tweety tweety 64 Jul 31 10:46 13 -> socket:[103712] l-wx------ 1 tweety tweety 64 Jul 31 10:46 19 -> pipe:[103723] l-wx------ 1 tweety tweety 64 Jul 31 10:46 2 -> /dev/null lr-x------ 1 tweety tweety 64 Jul 31 10:46 20 -> pipe:[103724] lrwx------ 1 tweety tweety 64 Jul 31 10:46 23 -> anon_inode:[eventfd] lr-x------ 1 tweety tweety 64 Jul 31 10:46 25 -> pipe:[103725] lr-x------ 1 tweety tweety 64 Jul 31 10:46 29 -> pipe:[103727] lrwx------ 1 tweety tweety 64 Jul 31 10:46 3 -> anon_inode:[eventfd] l-wx------ 1 tweety tweety 64 Jul 31 10:46 30 -> pipe:[103727] lr-x------ 1 tweety tweety 64 Jul 31 10:46 4 -> pipe:[103691] l-wx------ 1 tweety tweety 64 Jul 31 10:46 5 -> pipe:[103691] lrwx------ 1 tweety tweety 64 Jul 31 10:46 6 -> socket:[103692] lrwx------ 1 tweety tweety 64 Jul 31 10:46 7 -> socket:[103693] lrwx------ 1 tweety tweety 64 Jul 31 10:46 8 -> anon_inode:[eventfd] On the fedora 26 host system, I'm running: x2goclient-4.1.0.0-1.fc26.x86_64
