Hi Mike,

we followed your advice, increased the jcifs- loglevel and traced our 
application. Several days there where some exceptions, but jcifs did not hang.
This night jcifs had a severe problem, that caused loosing the connection
to remote share permanently. Could you pls have a look at this.

We traced the following:

Afterwards we traced only exceptions like the following one for about
20 minutes and then no more entries have been written since reboot of
our application.
