SIGSEGV in ssl3_get_message?

[Michael Menge]

Hi,

i have a Problem with Cyrus-Imapd 2.4.17 and libopenssl0_9_8-0.9.8j-0.62.1
openssl-0.9.8j-0.62.1 on a SLES 11 SP 3 (most recent versions for SLES 11)

We recently switched from a normal Cyrus to a Cluster Configuration
(aka Cyrus Murder). A frontend imapd will proxy the requests to the
backend where the mailbox is.

Some of these Frontend processes will trigger a SIGSEGV

I did run a bt on the core dump and it seems the SIGSEGV is in openssl.
I don't know if cyrus is not using openssl correct, of if it is only a
problem in openssl, but openssl should not trigger a SIGSEGV
