TCP/IP Stack Failure/max_session

I’m having a recurrent problem with my domino Server, after a few weeks working perfect, i got the message on the console “The TCP/IP protocol stack reported that it ran out of memory. Consult your network documentation to increase configured memory, or reduce Notes connections by limiting clients (see SERVER_MAXSESSIONS)”

After that the server goes unresponsible and even Windows Crashes, What to do? i restart the server and everything seems to be working, but always after a few days crashes again.

I changed the NIC, the Switch, The port in the Switch, mmm even I’d installed all the updates for windows server STD 2003, any idea? i can access the Notes databases, the main problem is that the server cannot send external email !! thats the main problem!

Pleas Help!! Here’s a brief explanation of the HW

Netserver DL380 dual processor Dual Core XEON.

8 Drives with an array in RAID5

4 GB of memory (i have 12 installed) for this server.

Two NICS GB Broadcom.


I have a dedicated disk partition to the lotus domino.


Please Any help!!!
