From time to time this what I get

12-02-2005 10:48:50 am: SERVER-5.70-0 [nmID=2000A]
Short term memory allocator is out of memory.
3131776 attempts to get more memory failed.
request size in bytes 4096 from Module NWPA.NLM

Could it be a leak in the NWPA.NLM, I am using Legato Networkr for
backup.This is an IBM xSeries 346 with Raid. Or do I need a firmware
update ? Nw6.5.3
