Sudden JVM crashes - a Postgres driver problem?

Hello,


we have a really tricky problem while running our web-application:

The JVM crashes from time to time for no apparent reason.
There seems to be no direct relation to any user-action, 
method-call or whatever.

We've checked the JVM crash dumps, but were not able to find something suspicious. The only ideas we've come up, were the 
usual suspects: JNI-calls and JDBC-Type2-drivers.

This is our current setup:
- JVM 1.4.2_09 on Linux SuSE 9.3
- mysql-database 4.1.14-max with 
- mysql-connector-java-3.0.14-production driver
- postgresql-database 8.0.3 with postgresql-8.0-312.jdbc3 driver

The only JNI-calls that I know of, is through some 3rd party UUID-library from "org.doomdark.jug". Maybe the forementioned 
jdbc-drivers contain JNI-calls, despite being Type4-drivers.

I've also checked a bunch of mailing-lists and it seems there are some outstanding bugs in hotspot, that may trigger the 
crash. Does anybody have more information or a workaround for this?


Who can help? Thanks in advance!
