[Pgpool-general] Problem with pgpool2 3.0.4 segfaulting

[John Workman]

Greetings,

Attempting to use pgpool2 in a production environment.

Unfortunately we have run into an issue where pgpool2 segfaults.

I've attached the debug output from syslog of this happening one time.





Here's an excerpt:

System is Linux (Debian 5.0) 32bit userland with x86_64 Kernel (Ubuntu's "2.6.32-30.59-server" kernel) This is from a production system. I can probably clone this to a quiet VM and reproduce the segfault under gdb or other tools if that's helpful.
