For the past one month, I have the following problem.

When I type :UNLOAD PROXY from the server console (to clean the proxy

cache later by typing :PROXY -CC), the BM server console hangs. And
loose communication with the server, and I could not do anything on
server except to reset it using the 'reset' button. No abend messages,
error messages on the console.

BM version is BM 3.6 Ent Edition, server is NW 5.1 SP4.

I am able to unload proxy as soon as the server reboots, but not after

even one day. (I did not test unloading it after one hr or so from
time, since it is a live server).

Any solution?
