[BUGS] Hangs on Semop

[Gary Mensenares]

Hello all!   I was just wondering if anyone else here has ever experienced Postgres hanging on an INSERT or DELETE command?   Here is my setup: DB:       Postgres 7.3.4 OS:      Fedora Core 1 Kernel:  2.4.22   The behavior is quite erratic. Using the exact same test script, sometimes it runs and sometimes it hangs so it is rather difficult to recreate the condition. We did an strace on postgres and got this:   postgres 14648  0.0  0.7 12524 4012 pts/2    S    03:30   0:00 postgres: jug ubp [local] DELETE waiting   #strace -p 14648 Process 14648 attached - interrupt to quit semop(851970, 0xbfe2bce0, 1   Nothing extraordinary shows up on the postgres logs itself.   Thanks for whatever help you can extend!
