nsrmmdbd does not release memory

Question

New problem, backups have apparently previously been working fine.

NW Server running Win2000 with SP4 and NW 7.2.1 for windows.

As backups proceed, the amount of memory used by the nsrmmdbd process grows steadily until it interferes with the basic memory requirements for the server which then hangs.

After a reboot, everything is back to normal.

Also, if NW services are restarted, the memory is released.

A small to medium backup succeeds, but the memory which has been allocated to nsrmmdbd does not get released.

The next backup causes the memory allocated to nsrmmdbd to start growing from the previous level. Finally, too much memory is used and the server hangs.

Has anyone seen this and resolved it ?

The knowledgebase does not seem to show anything directly related.

Thanks

Update to latest patch release for 7.2.x (that would be 7.2.2) and if the same happens again you should probably open up this with support.

Good thing to do would be to check what changes have been done to system if apparently everything was fine until now. Perhaps some change triggered this behavior.

Thanks for any help offered. The problem is resolved.

Curiously, although the memory was being hogged by nsrmmdbd, it was not a media DB problem. Rolling back the media DB using mmrecov did not resolve the problem. Nor did "rebuilding" (scavenging) the media index.

Finally a complete DR to a point 2 weeks ago resolved it, and we are busy scanning in the intervening volumes.

So it points to a client file index corruption.
