SMTP: Err Msg: Insufficient Memory (105290)
The information in this article applies to:
- Microsoft Mail Gateway to SMTP 3.0
This article was previously published under Q105290 SYMPTOMS
Microsoft Mail Gateway to SMTP displays the error message:
Insufficient memory
CAUSE
This error usually is seen when a message has more than 300 recipients
and the SMTP gateway has low memory available in the conventional 640k RAM.
System requirements place a strain on the available conventional memory.
The SMTP Gateway code requires different amounts of memory depending on
which TCP/IP stack is used, and the TCP/IP stack must also be loaded,
although it can be loaded high if memory is available. Finally, the
Gateway's configuration files and the postoffice routing files are also
loaded:
LOCAL.CFG
ADDR_MAP.CFG
NETWORK.GLB
*.XTN (All files in the XTN directory)
GROUP.GLB
ACCESS2.GLB
If the Gateway postoffice has many mailboxes and the Gateway serves
many downstream postoffices, the amount of memory left for processing
mail messages can become unacceptably low.
This error will also be returned if there is a corrupt *.P1 file in the P1
directory.
RESOLUTION
Unfortunately, there are so many variables involved that it is very
difficult to provide enough memory to process messages under all
conditions.
But there are two ways to provide the Gateway with more working memory
to handle large messages and user lists: you can load MS-DOS, the network
operating system, and the TCP/IP software above the 640k conventional
memory, and you can reduce the size of the ACCESS2.GLB and GROUP.GLB files
by moving users off the Gateway postoffice and deleting unused groups.
If there is a corrupt .P1 file, clearing the *.P1 files from the P1
directory will usually resolve the problem.
