FreeBSD 13.0-RC4 and Nginx process "stuck" during restart

[Christos Chatzaras]

Hello,


I upgrade from 12.2 to 13.0-RC4 and I notice a strange issue with Nginx.

When I run "service nginx restart" in some (random) servers it doesn't complete the restart and it "stucks" at "Waiting for PIDS: 20536." .

I can kill the 20536 process and then restart completes.


procstat -kk 20536:

  PID    TID COMM                TDNAME              KSTACK

I found this commit:

https://cgit.freebsd.org/src/commit/?id=dbec10e08808e375365fb2a2462f306e0cdfda32 <https://cgit.freebsd.org/src/commit/?id=dbec10e08808e375365fb2a2462f306e0cdfda32>

Could this be related? If yes can we have the patch in releng/13.0 ?


Kind regards,
