Hi Liat,

So if the JVM process is growing up to 8GB, I would guess that there is a memory leak \
in some of the underlying libraries of the JVM or the JVM itself. Java 6u30 is pretty \
old and I remember some leaks in the JVM around SSL (but I don't recall which \
version). I would suggest that you give a try to a more recent JVM. I don't think the \
issue is coming from OpenDJ itself.

Kind regards,

Ludovic.
