Niclas Hedhman commented on PAXLOGGING-20:
------------------------------------------
Proposed fix;
If we just buffer the configuration in the update() method, and call the
configure() during a log call instead, it should solve this particular problem.
That is a fairly low impact workaround, which solves this particular problem.
Alternate;
The Log Service backend could have its own thread, for all calls into the Log4J
backend. This guarantees only a single lock in the call, hence deadlock free.

> Project: Pax Logging
> Issue Type: Bug
> Affects Versions: 0.9.6
> Environment: Felix 1.0.0, Windows XP Pro, Intel Core2 Duo T7500, 2.20

> Once we upgraded our laptops to a dual-core we started having many, many
> lockups that seem to be related to the interplay between pax-logging and
> R4SearchPolicyCore. Below is our log output, followed by a thread dump
> detailing the deadlock.
