Hi,

I'm seeing issues with PG9.1.3 segmentation faulting.
The postgresql logs suggest issues with the JVM launch as in the extract
below:

2012-09-07 14:18:38 BST [29481]: [17611] user=xxxxxxx,db=prodDEBUG:  00000:

postmaster.c:2354
2012-09-07 14:18:38 BST [20702]: [45051] user=,db=DEBUG:  00000: server
process (PID 29481) was terminated by signal 11: Segmentation fault

This is using pljava 1.4.3 and IBM Java 6 (64bit).
Physical server running RHEL 6.1 

I have a java core file which suggests out of memory but I didn't expect
this to knock out the rest of the DB.

Anyone seen anything similar?

Thanks

When a postgresql backend process dies unexpectedly, the postmaster
will shut down all other backends as well, and restart operation from
there. This is to make sure the dying backend did not mess with the
shared memory.
