Hi,
My system: debian wheeze, urbackup server v1.2.2, every client v1.2.

I have problem with /usr/sbin/urbackup_srv service . It just stop working after a few days. I have to start it manually over and over.

I have notice strange logs on /var/log/kern.log
kernel: [506550.166045] urbackup_srv[19242]: segfault at 7f6bc6d98440 ip 0000000000426bfa sp 00007f6bc67abdc0 error 4 in urbackup_srv[400000+e7000]
kernel: [506785.694405] urbackup_srv[19414]: segfault at a8 ip 00007f149af29c05 sp 00007f1493b7dbc0 error 4 in liburbackupserver.so.0.0.0[7f149ae27000+156000]

Please help to solve a problem

Best regards,

Donatas

Can you enable debug logging ( http://www.urbackup.org/Administration_Manual.php#x1-500008.2 ) and post the last messages in /var/log/urbackup.log . Maybe that will give us a hint where the error occurs.

Then it would be helpfull if you compile UrBackup using the sources, and run it in gdb. You can do that by replacing the “exec” in last line in /usr/sbin/start_urbackup_server with “gdb --args”. I usually run it in screen. Once the server crashes the output of the “bt” command in gdb will probably help to narrow down the problem.

Alternatively/Additionally it would be helpful if you post everything out of the ordinary that you are doing, e.g., config that you changed from the default, such that the problem can be reproduced in the testing environment.
