I tried to follow the instructions in the link you sent, but it didn’t seem to help. Here’s what I did:
gitlab-ctl status to get the unicorn pid:
run: unicorn: (pid 1590) 44s; run: log: (pid 611) 160999s`
I tried to run
gdb -p 1590 and it would not attach, (no such process). I tried then
gdb -p 611 and then
call (void) rb_backtrace() and it said
No symbol table is loaded. Use the "file" command.
I tried then to use
htop to determine the pid of the unicorn process that was hogging all the CPU, which also said no such process.
Trying the following heading, Troubleshooting without affecting other users, wasn’t possible. It says to get some token from Profile Settings -> Access Tokens, but no URLs load without producing the 502.
I tried also increasing
unicorn['worker_timeout'] = 300, which does not seem to have any effect.
Despite all of the above, I have still tried perusing the logs in
/var/log/gitlab/unicorn/unicorn_stderr.log and only seem to get
/opt/gitlab/embedded/service/gitlab-rails/lib/gitlab.rb:31: warning: already initialized constant Gitlab::VERSION. Googling this hasn’t brought much info
