Hi,
I have been fighting with OOMEs and yesterday I was able to
track down the cause.
There are lot of ConcurrentReaderHashMap entries and it seems that something is repeating itself.
I have heapdump (about 300MB) which can be analyzed using MDD4J for IBM JVM. I can provide them for further investigation.
Br,
Juha Moisio
