nsrjobd.exe on networker server crashes when savepnpc oracle backups are running

We have a Windows server 2008 R2 SP1 server with NetWorker version 7.6.5.3.Build.1195 running on it.

2/3 times a month the nsrjobd.exe crashes when running oracle on AIX savepnpc backups.

I have already made several networker updates in the last months and the windows server is patched to the latest level. Nothing works.

Here is the report.wer from last night:
