> Dear Appache Community,
> We are using Jackrabbit 1.6.0 as a document store for our app running on JBoss5.1.
> Since we started to use Jackrabbit more intensively, deadlocks in Jackrabbit internals occur.
> Something inside is locked (for unknown reason) which lead to infinite blocking all threads which want to use Jackrabbit.
> On production environment the deadlock occurs every day and only JBoss restart helps.
> Unfortunately I have no scenario to reproduce problem. 
> The thread dump which shows dependencies between blocking threads is enclosed.    
> I found similar bug solved in JCR-2554 but I am not sure whether relates to the same problem.
> Could you please confirm that this is a JCR bug. And if so, is it repaired 1.6.5 version or does exist any workaround?
> Thank you very much,
> PS
