Netserver LH3 has memory leak

[William Harrington_1]

Our print and file server a Netserver LH3 P11_400 MHZ with 1023MB of RAM locks the users out after it has been running for 5 days. On that fifth day the users will not be able to access their files (not available), the server is up and running and appears normal. When it is rebooted every thing is back to normal and it seems to run fine although we did remove the Sure Store DLT80 from the machine because it would not boot if the DLT was connected, the same scsi runs the RAID array.
Any suggestions on how to find the source of the problem, the event logs do not give a clue.
