Hi All,

I hit a hang issue in postgres 8.4 query. Hit this issue multiple time on HP-UX. Below is the snapshot of the hang thread.

-------------------------------- lwpid : 600943 -------------------------------
0: c00000000054ced0 : _poll_sys() + 0x30 (/usr/lib/hpux64/libc.so.1)
1: c000000000561560 : poll() + 0xe0 (/usr/lib/hpux64/libc.so.1)
2: c000000001f798e0 : pqSocketPoll() at fe-misc.c:1079
3: c000000001f790e0 : pqWait() at fe-misc.c:1024
4: c000000001f6ebb0 : PQgetResult() at fe-exec.c:1554
5: c000000001f6f0a0 : PQexec() at fe-exec.c:1735

Is it a known issue? Any possible workaround ?

Thanks & Regards,
Devendra Singh
