<p class="MsoNormal"><span style="font-size:12.0pt">You might take a look at the file system manager nodes (mmlsmgr) and see if any of them are having problems. It looks like some previous “mmdf” command was launched and got hung up (and perhaps was terminated
by ctrl-c) and the helper process is still running. I have seen mmdf get hung up before, and it’s (almost always) associated with the file system manager node in some way. And I’ve had a few PMRs open on this (vers 4.1, early 4.2) – I have not seen this on
any of the latest code levels)<o:p></o:p></span></p>
