[Exist-open] eXist and Norton Anti-Virus

[Legend of t. D. <lot...@ya...>]

Team,

I have a client using eXist 1.4.0 on Jetty on a Windows VM that has Norton Anti-Virus running.  Occasionally, when the AV runs, the eXist application becomes non-responsive and does not recover.  The error is consistently happening during an AV check, but is not happening every time that AV checks.

Notably, during the AV check, the CPU spikes to 100% at times.  However, we have done a lot of testing to prove that eXist does not become unresponsive when the CPU spikes to 100% on a system due to high priority tasks (to the point of running a test app for 20 minutes in "real-time" priority, which completely blacks out the system, and at the end, eXist is still kicking).

The non-responsiveness eventually forces the service to be restarted, and always results in a corrupt database.

Has anyone seen this before or have any suggestions on how to proceed?  Turning off the AV is not an option.

Thanks,
Lothy
