Bug reference:      6342
Logged by:          Andrea Grassi

PostgreSQL version: 8.4.8
Operating system:   SUSE SLES 10 SP4 64 BIT
Description:

Hi,
I have a big and strange problem. Sometimes, libpq remains blocked in “poll”
function even if the server has already answered to the query. If I attach
to the process using kdbg I found this stack:

__kernel_vsyscall()
poll()                          from /lib/libc.so.6

Actually, even better, can you show the full kernel stack of your test program when it's blocked? cat /proc/$pid/stack .
