Be aware of JDK 1.6.0_30 with BPM or SOA on Windows Server

Have not done extensive testing of this, but I have noticed on a few BPM installs on Windows Server 2008 R2 and also on Windows 7 – both 64-bit – that BPM is very unstable with JDK 1.6.0_30 (64-bit).  By unstable I mean slow and crashes with an OutOfMemory or similar after 10-15 minutes of use.

I have found on these systems that changing to 1.6.0_26 fixed all problems and dramatically improved performance.  So that is what I did!  As I said, this is not scientific, I did not do extensive testing or work out why it was having problems – at the time I did not have the time to spare, I just needed it fixed.  But I am posting it anyway just in case it helps someone out.

Note that I have not seen this issue on any other operating system.
