Thread: 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!

Hello! I think you'll want to redirect this to the JDBC list. This list is about discussing the postgresql website itself.

Thanks, you are right. Didn't realize that there is a list of this name. R. -----Ursprüngliche Nachricht----- Von: Magnus Hagander [mailto:mha@sollentuna.net] Gesendet: Donnerstag, 13.
