[Pgpool-general] pgpool-II child process is segfaulting

[Tatsuo Ishii]

> Hello Tatsuo, How I can download the latest stable release of pgpool-II 3.1, with the latest modifications developed?

3.1 stable is tagged as "V3_1_STABLE". You can get it from CVS
repository by specifiying the tag.  See
http://pgfoundry.org/scm/?group_id=1000055 for more details.

In the mean time I have sent you the tar ball via private email for just in case.

>> Hallo,
>> 
>> we have a Java application that is executing a larger sequence of SQL operations including table manipulations and content modifications within one connection. When we are running these operations through pgpool-II, the pgpool child process handling it always dies with a segmentation fault. But it's not always the same SQL Statement that is causing the segfault.
>> 
>> Our setup is as follows:
>> - pgpool-II-3.1 on a Linux-x86_64 server. We also encountered the segmentation fault with pgpool-II-3.0.4 before trying out version 3.1.
>> - the pgpool configuration is reduced to a minimum, that is the connection cache, the master slave and the load balance mode are off. The replication mode is enabled but only one backend is defined.
>> - PostgreSQL server version is 9.0.4
>> - the Java application uses the postgreSQL JDBC driver in version 9.0.801
>> 
>> Do you have an idea what might be causing this behavior?
>> 
>> For some additional details I attached a backtrace. I can also provide the debug messages of the child process, if you want to have look at them.
>> 
>> Thanks in advance.
