What is the version of openssl?
It seems known problem of ruby 2.1.1.
Please try ruby 2.1.2.

[pinfieldharm (Paul Infield-Harm)]

• File sidekiq.log.1 sidekiq.log.1 added

We also have the same problem, even after upgrading to ruby 2.1.2. I've attached the logging output. I can supply a core dump if that helps.

This has been happening on a regular basis (once every few days) for a few months, at least.

The version of openssl we're using is a recent version of openssl 1.0.1 on Ubuntu:

$ openssl version -a
OpenSSL 1.0.1 14 Mar 2012
built on: Mon Apr 7 20:33:29 UTC 2014
platform: debian-amd64

OPENSSLDIR: "/usr/lib/ssl"

Also: Is there a way to change the priority? I'm not the original reporter, but this particular bug is causing a lot of problems at my company.

• Is duplicate of Bug #9592: Fix segfault with old OpenSSL added

[rhenium (Kazuki Yamaguchi)]

• Status changed from Feedback to Rejected
• Assignee deleted (linux)

This should have been fixed at [Bug #9592]. I suspect Paul's is another issue ([Bug #12292]), though, I can't tell without a reproducer.
