Re: Sudden JVM crashes - a Postgres driver problem?

Hi Robert,

I might be totally wrong, but I've had some problem with SuSE
distribution like this, and could get to stop it with the help of the
hotspot team.
Just as a test, comment out any appearances of ldap in
/etc/nsswitch.conf. Sounds very strange, but try it. If it works, you
have to set LDPRELOAD to a $JAVA_HOME/jre/lib/$ARCH/libjsig.so.

hope that helps...
