[Pgpool-general] pgpool segfaulting and dumping core

[Tatsuo Ishii]

> Greetings,
> I'm running pgpool-II-3.0.4 on a Linux-x86_64 server, which is load
> balancing for a cluster of 3 PostgreSQL-9.0.4 servers (1 master, 2
> standby).  I'm using pgpool for load balancing only (not managing
> streaming replication or failover).  Last night, pgpool started

Yes, I'm interested. Please show me a backtrace.
