[Pgpool-general] FW: Child process was terminated by segmentation fault

[Silvio Svečnjak]

Hello!

 

We're using pgpool 3.1 with PostgreSQL 8.4.7 on RHEL 5.3 x64 where pgpool is configured for replication only on 2 backends. Pgpool is used by a real time java application which occasionally (without any visible pattern) catches an exception (org.postgresql.util.PSQLException: An I/O error occured while sending to the backend). 

 

We've determined that the exception is caused by pgpool as at the same time pgpool records the following error: 

 

2011-11-14 14:14:45 ERROR: pid 10783: Child process 10812 was terminated by segmentation fault

2011-11-14 14:14:45 DEBUG: pid 10783: child 10812 exits with status 11 by signal 11

 

Bigger chunk of  log file is enclosed as well as the pgpool configuration file.

 

After some research on the mailing lists, I found that some patches have been released for version 3.1 which may resolve the issue. So I downloaded and deployed the latest stable release pgpool2-V3_1_STABLE-8b47d55, but it didn't solve the problem. 

 

I would appreciate very much if someone could provide any help with this? Thank you in advance,
