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.
What about the stack trace? It might help isolate the problem.
This is our current setup:
- JVM 1.4.2_09 on Linux SuSE 9.3
Fine.
- 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
No objections here.
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.
Both of those are Type-4 and are, therefore, pure Java.
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?
Can you somehow turn off that suspect UUID library? See if JVM crashes.
Plus a stack trace of all JVM threads would be helpful.
Nix.
