Hello. Thanks for the report. Could you share unit.log with the alert?

[centminmod]

Log doesn't seem to have much useful info though all i see is

@centminmod Thanks, but this log definitely comes from Unit that was compiled without debug.
When Unit is compiled with --debug option, the unit.log contains hundreds of [debug] lines.

Could you please check that you run the same Unit, that you have compiled and where's its log?

[centminmod]

Yeah i first compiled without --debug, then compiled with --debug and that is all that is available in the same log - nothing else.

Not sure if you missed it but centos 7 systemd service status did log the debug output if that is what you're looking for ? Looks like on centos 7, debug out isn't in the log itself.

[VBart]

@centminmod These are only the first few lines that are logged to STDOUT before Unit opens unit.log.

Note also that all lines with debug have time 05:29, while the lines you showed from log have time 05:05.

[centminmod]

Yeah I noticed unfortunately after debug version compiled, the unit.log is empty for me - nothing gets added to the unit log. Will try again when I wake up :)

[centminmod]

Looks like 2 problems

• the unitd socket caused address already used error so unitd didn't start up so no entries were added to log
• when i removed the unitd socket manually to start up unitd, the unitd log filled with debug errors listed below

/opt/unit/sbin/unitd --version
unit version: 1.0
configured as ./configure --prefix=/opt/unit --pid=/run/unitd.pid --log=/var/log/unitd.log --modules=modules --user=nginx --group=nginx --state=state --debug --cc-opt='-O3 -fstack-protector-strong -fuse-ld=gold -Wimplicit-fallthrough=0 -fcode-hoisting'

systemctl start unitd
Job for unitd.service failed because the control process exited with error code. See "systemctl status unitd.service" and "journalctl -xe" for details.

@centminmod It seems, the socket was left because of abnormal Unit exit due to crash.

From the debug log I see that the discovery process that checks language modules was crashed trying to load one of them.

You may try to remove modules from /opt/unit/modules/ one by one in order to identify the culprit. Also a core dump or running unitd with gdb in order to get backtrace will help.

@centminmod Well, I've found the problem. It caused by two modules with the same language and version.

Here is the fix:

sweet @VBart another bug squashed 😁

[VBart]

@centminmod Thank you for spotting this issue. The fix was committed.
