[pgpool-general: 2365] Re: Pgpool 3.3.1 segfault error

[Yugo Nagata]

Hello,

For analysis, could you please provide us the following information?

- OS and its version
- pgpool.conf
- detailed log including messages before segfault
- procedures to reproduce this (if you know)

In addition, if you have a core file, please get a backtrace as follows:

 % gdb pgpool core-file
  (gdb) bt
