    jboss 3.04 and hibernate 2

      Hi,
      We are using jboss 3.04 with hibernate 2 and have a scheduled task running nightly which inserts data into an oracle 10g database. Over the past 4 months this process has caused the jvm to crash 3 times. The volume of data being inserted into the database was small in all cases.
      The following was retrieved from the log file:

      Unexpected Signal : 11 occurred at PC=0x40565659
      Function=(null)+0x40565659
      Library=/usr/local/bin/j2sdk1.4.2/jre/lib/i386/server/libjvm.so

      To me this looks like it could be a memory issue, though our sys admin informs me that there is plenty available memory on the machine.
      Does anyone know if there are any documented problems with these versions of jboss, hibernate and oracle. Would it be worth upgrading to jboss 4 and hibernate 3?

      Any info would be greatly appreciated.
      Cheers
