Cron error "/usr/bin/python3': corrupted double-linked list"


I’ve been running a GitLab server successfully for about 2-3 months with no problems. It’s just a basic Omnibus install with no addons. The server is running Ubuntu 14.04 and only GitLab. Yesterday I started receiving e-mails like this:

*** Error in `/usr/bin/python3’: corrupted double-linked list: 0x00000000019e7c20 ***
Aborted (core dumped)

I got a similar one this morning and I can’t figure out what is wrong. Google doesn’t help much. Has anyone seen anything like this before?

Thank you,
