First of all, thanks for you answer.
You are right, I also think that's a problem of memory allocation in Windows Server. I just tried to set the page file size to 0, but JV refuse to start.
Is very strange:
when the OOME errors occurs and the overloaded JavaService process hangs, the paging file usage peak is 100%, but the "peak mem usage" value of task manager is always 512MB for all JavaService processes! It seems that windows does not use more thank 512MB (the exact value of maxpermsize), nerver! I'm a bit frustrated, i read all 73 pages of this forum and searched all the web without find any answer.
