Hello,
i just wonder whether anybody else has seen this ...

All of a sudden, our NW server (W2K8R2 SP1, NW 7.6.2.5 & 7.6.3.5) is incapable 
to control (remote) devices. 
Since a while this happens about once a month. 
Unfortunately, as the system is very powerful, you will not even notice it 
immediately. 
What happens is obviously this:

  - NW fails to monitor/control the devices on one of our two SNs.
  - In fact, all nsrmmds will die on the first one while nsrexecd is still 
running.
  - Other backups running to the other SN are still fine.
  - On the NW server, NW will fill the /tmp and/or the /tmp/sec directory very 
fast with hundred thousands or more than a million LCK files. As EMC told me, 
their names refer to the device monitoring process.
  - Restarting the NW services at the 'defective' SN does not help - no nsrmmds 
will be restarted here later.
  - You must either restart the NW services at the NW server or reboot the 
machine to make the environment work again.
  - Finally, do not forget to delete all these LCK files.

I do not really expect a solution for this phenomenon - i just want to know 
whether anybody else from the community has experienced the same problem.

Any feedback appreciated.
