Lots Of Tcp_smtp_server Cores On Two New Systems With MS 8.0.1.1 Installed

(Doc ID 2188805.1)

Last updated on JULY 19, 2017

Applies to:

Oracle Communications Messaging Server - Version 8.0.1 and later
Information in this document applies to any platform.

Symptoms

Experiencing as many as 40 tcp_smtp_server cores within 12 hours on two new systems.

Two of our four new backend stores logged over 40 tcp_smtp_server cores, each, with very little number of users and mostly idle.

The impact of so many cores will eventually result in filling up disk space and bringing down the server.

Changes

Enable libumem on MS dispatcher process in order to capture the necessary data to see memory corruption. See KM doc: 1383299.1
