Is it slowing down mail flow?

Do you see any errors similar to these?

[27224] An error occurred while decomposing a message.
[10001] Malloc error while attempting to allocate 7908031 bytes.
[10004] File write error.

If yes, then you may be running into a know issue reported in the following KB article:

http://www.symantec.com/docs/TECH164155

The KB also suggests a workaround to mitigate the issue.

Dear TSE-JDavis

Mail flow is not slowing down but i need to know the root cause of this issue. (i.e It's happen because inbound or outbound)

Dear AdnanH

I don't see any error.

Please advise.

Issues like this are harder to troublehsoot without looking at the proper evidence, so the best option is to contact support with a diagnostics from SMG.

Thanks
