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 63094 100505 nginx - mi_switch+0xc1 = sleepq_catch_signals+0x2e6 sleepq_wait_sig+0x9 _sleep+0x1be = kern_sigsuspend+0x164 sys_sigsuspend+0x31 amd64_syscall+0x10c = fast_syscall_common+0xf8=20 I found this commit: = https://cgit.freebsd.org/src/commit/?id=3Ddbec10e08808e375365fb2a2462f306e= 0cdfda32 = Could this be related?
