Frequent Imap Crash On Linux Stores

(Doc ID 2180988.1)

Last updated on MAY 02, 2018

Applies to:

Oracle Communications Messaging Server - Version 7.0.5 to 7.0.5 [Release 7.0.0]
Information in this document applies to any platform.


Linux Messaging Server Store running:
Oracle Communications Messaging Server 64bit (built Feb 26 2016) 64bit (built 06:34:15, Feb 26 2016)

Seeing frequent IMAP process crashes on the Linux stores only around 3 minutes after every restart; compared to Solaris OS stores which are running fine.

The dmesg log shows:

imapd[23099]: segfault at 0 ip 00007fe82154c82f sp 00007fe7fc0234b8 error 4 in[7fe821419000+18a000]

On the Linux platform, disabling ISS via = 0 causes imap to crash after paired ISS hosts to these stores went down due to a hardware failure. This does not happen on the Solaris platform.
