Summary0005074: Failed to start sogo service
Description

After package updates, sogo failed to start, no error on console or the output of "systemctl status sogod.service" command. but /var/log/messages contains one error line:

Jul  8 12:33:20 mail kernel: sogod[19319]: segfault at 7ffd721bcb38 ip 00007fcb1b68a9cf sp 00007ffd721bcb20 error 6 in libgnustep-base.so.1.24.9[7fcb1b2f8000+4dc000]

Package gnustep-base was installed from EPEL repo, version 1.24.9-1.el7. I tried the gnustep packages in SOGo repo, it didn't raise segfault error like above log line, but it just hangs there and never start sogo service and put it to background.

Any idea to fix this issue?

Dear @ludovic,

Could you help take a look at the full trace stack? Thanks. :)

Looks like a GNUstep issue, not a SOGo issue. Check your sogo.conf for "weird" characters.

You mean sogo.conf file may contain invalid characters somewhere?

Any recommend tool/command to help check invalid character in sogo.conf? Or have to check line by line manually?

I copied sogo.conf from a working machine, replaced SQL related values, restart sogod service. In syslog, i got this:

Jul 9 19:38:50 mail kernel: sogod[15385]: segfault at 7ffd7bb86ff8 ip 00007feac7f419eb sp 00007ffd7bb86ff0 error 6 in libgnustep-base.so.1.24.9[7feac7baf000+4dc000]
Jul 9 19:38:50 mail systemd: Can't open PID file /var/run/sogo/sogo.pid (yet?) after start: No such file or directory

Directory /var/run/sogo/ is set to 0777 (for testing purpose), still this error. It also seems not caused by "weird" characters in sogo.conf since same config file works on another CentOS 7 server.

Any idea?

Then try the same GNUstep version as the other CentOS 7 box. As I said, it's not a SOGo bug.

Both runs same gnustep version from EPEL repo.
