JVM is performing abort shutdown sequence

Hello,I just upgraded im my test environment a domino server from 5.12 to 6.52 version (6.51 + incremental); my test is good unless for these reasons: the shutdown of the http task (and domino server too obviously) causes the error:

“JVMXM004: JVM is performing abort shutdown sequence” and the start of NSD process…

I am not using Java agents, servlets etc…

Is it possible, for temporary workaround, to load http task without JVM?

In the server document “Java servlet support:” is set to “None”, but the JVM is loaded with http…

Someone can help me?

Thank You in advance,

Davide
