We have a problem with a deadlock in Jackrabbit. We are using version
1.2.1 with some modifications to use a Oracle connection through JNDI.
Now we have a deadlock in the DatabasePersistenceManager. Can someone
explain to me what we're doing wrong.
well that's going to be very difficult without knowing what exactly
you're doing
and what exactly your modifcations consist of ;) we'd also need a jvm thread
dump including all threads involved in the dead lock.
btw: are you also experiencing dead locks with an out-of-the-box jackrabbit
release?
cheers
