Hi Alex,
Thank you for the heads up. I was not aware of deadlocks occuring in
prudent mode. Can you tell us more about your environment, OS version,
file system sharing technology, etc? For example, what do you man by
"ownership of the drive"?
Cheers,

Just a heads up: we had a similar usecase at a client, but unfortunatly
they were using a windows cluster where one node owned the shared drive
where the logs had to be written to. The problem was that when you
switched ownership of the drive while the application was logging in
prudent mode, the file lock could not always be released. This means the
next time you tried to log, the blocking lock() call would hang
infinitely. After this happened a few times (caught it before production
luckily), we wrote custom appenders with non-blocking locking and now we
usually log asynchronously which avoids the problem alltogether (no
prudent mode needed).

As David mentioned prudent mode caters for this use case. It should
should work nicely.
BTW, I did not see get the original message from "LogbackUser"
apparently posted from nabble.

Are there any configuration properties through which multiple
web-applications using logback could be configured to log to
the same log
file? This is taking into consideration that the messages
would be logged
concurrently without losing any messages.
The reason I ask this question is that - we have a clustered
environment
of glassfish server instances where the same web application
is installed
on all the server instances in the cluster.
