McAfee NetShield 4.5 and Oracle

I am having an interesting problem with regards to Netshield 4.5.1 and Oracle8.1.7 on Win2K. We have a 3rd party app that generates a trace file due to deadlock issue. When NetShield is enabled with the Oracle drives (data and ORACLE_HOMEs) excluded from the scan, we have a severe performance loss and the db hangs for about 10 minutes while the trace file is generated. As soion as the trace file is generated, performance returns to normal. We can reproduce this every time using the same test.

When we disable NetShield, the deadlock occurs, the tracefile is generated and we do not even realize it has happenend. There is no performance loss at all.

We are going to test by excluding all drives from the scan and removing one drive to determine if we can pinpoint where the rogue scanning might be occuring.

Has anyone ever experienced this and if so, how was it resolved?

Thanks very much.
