Total server work memory

We are running Netware 5.0 with Sp6a and ARCServe 6.6 sp4
on a dual P3 intel board with a adaptec 3210S controller for the HDD's
and a 2940u2w for a dat-streamer (HP-dat40i)

the server memory statistics after a restart are :

Allocated memory pool, in bytes:              22.953.984         2%
Cache buffer memory, in bytes:              966.758.400       90%
Cache movable memory, in bytes:                           0        0%
Cache non-movable memory, in bytes:        1.282.048        0%
Code and data memory, in bytes:              80.216.064        8%
Total server work memory, in bytes:     1.071.210.496     100%

but when running the server a few days the "total server work memory" gets lower and lower
and around 90 days after the restart the statistics says:

Allocated memory pool, in bytes:               28.471.296        3%
Cache buffer memory, in bytes:               966.881.280    104%
Cache movable memory, in bytes:                            0       0%
Cache non-movable memory, in bytes:         1.298.432       0%
Code and data memory, in bytes:          4.226.285.568     4294
Total server work memory, in bytes:        927.969.280    100%

anyone has any idea whats wrong ?

You have something that is chewing up memory.  Since you are exceeding 100% I'd guess that you're using a lot of swapfile space - have you checked the virtual memory stats?

You probably have a program with a memory leak.  Do you eventually start getting memory allocation errors?

What DS are you running?  Do you have any other programs running, like GroupWise, ZENworks, NDPS, NAMED, DHCP server, management portal, web server, etc?  When did this start happening?

Oh, by the way, NetWare 5 didn't really take full advantage of dual processors.  Proc 0 ended up doing all the work, while Proc1 just handled interrupts, unless you had an MP-enabled product running on it, like GroupWise.  To truly take advantage of the investment in a dual-processor system, you should upgrade to NetWare 6 at least.  NetWare 5.0 is on the verge of being EOL'ed if it hasn't been already, and 5.1 won't be far behind.

DS 7.51 running (had trouble updateing to 8.xx so i wanted to keep the old one )
also running SAGE KHK server(data base for a financial accounting software)
and a radio clock for the timesync


Virtual Mem dosent look aktiv to me
Page-in or out is 0
Swap pages are 512 and 512 are free
no Page faults

Using 2.048kb swap file size for the sys volume the Data volume not listed.

Address Space "OS"
Allocated mem is around 25MB 9% not in use.

Was wondering about my processors too , dident know its that bad but at last the server is very stable

Do you have 1GB physical RAM?

Yes. I have 1GB Ram.

I started stoping some programms when possible to find the leak.
I lose around 40-70kb every 5-10mins.

In Monitor, if you go into "loaded modules" and sort by bytes used, you can tell which module is taking the memory...

This TID talks about memory leak with 1GB ram, using NetWare 5.1 SP3.  If the check of loaded modules shows "thejudge.nlm" taking your memory, then it's probably the same problem.

Memory Leak!

use MONITOR and select LOADED MODULES to see how much memory any one process is taking up - they guy with the most amount of memory used up is your culprit.

and having dual proc's in a NetWare 5.x server is NOT bad - they just aren't really doing anything beyond the first processor UNLESS the server is running an application that takes advantage of more than one processor (ie:  GroupWise, Oracle, etc.)

Server.nlm
DS
MM
Filesys
Pserver
......

The TID describes exactly the problem that i have but there is no thejudge.nlm loaded on my system ( but its in the system directory ) , maybe the server loads it only on startup and unloads it self ? i try rename and restart

thx ShineOn
