I enabled the POST transactions, and all of a sudden, the apache process is now hung (this is first time I'm seeing this behaviour).. The stack is :
(gdb) t 21 [Switching to thread 21 (system thread 29207)] #0 0xc000000000306850:0 in _semop_sys+0x30 () from /usr/lib/hpux64/libc.so.1 (gdb) bt #0 0xc000000000306850:0 in _semop_sys+0x30 () from /usr/lib/hpux64/libc.so.1 #1 0xc000000000314b50:0 in semop+0xb0 () from /usr/lib/hpux64/libc.so.1 #2 0xc000000001b73220:0 in proc_mutex_sysv_acquire+0x70 () from /opt/hpws/apache/lib/libapr-0.sl.9 #3 0xc000000001b73fc0:0 in apr_proc_mutex_lock+0x60 () from /opt/hpws/apache/lib/libapr-0.sl.9 #4 0xc000000001b72950:0 in apr_global_mutex_lock+0x90 () from /opt/hpws/apache/lib/libapr-0.sl.9 #5 0xc000000001cf37d0:0 in do_post+0x780 ()
Two possibilities:
* the command/Fetch URI is stuck also, or
* something died holding the post lock, and it didn't get automagically cleaned up. I recall hearing that SysV sems are notorious for that on some platforms.
Do either of those make sense? Any clues in the error_log?
