[Pljava-dev] java.lang.OutOfMemoryError

Hello,

we use now pljava 1.3 and postgres 8.1.4
we can't use java 1.5 because it depends on xmlrpc 3 which is an alpha
version.

The problem is still there.

We have a big treatment and after a long time, we have this outOfMemory.
We print the warning on the statement :
ERROR - ====>org.postgresql.pljava.internal.ServerException:
java.lang.OutOfMemoryErrorjava.lang.OutOfMemoryError
INFO - Statement WarningWARNING: buffer refcount leak: [779]
(rel=1663/16440/52989, blockNum=3, flags=0x27, refcount=1 2)

What could be this buffer refcount leak.

Is the "buffer refcount leak" the cause of the OufOfMemoryError or its
consequence ?

This long treatment is OK if we have the option : -Xmx512M
If we use -Xmx8M, it crash more quickly !

Thanks for your help

Eric
