> Hello, we are having random crashes on all of our servers.
> According to the backtrace from the core dump, it is happening during a do_refresh in the calendar module.
> While most of the crashes happened at midnight, there are exceptions (with similar backtraces)
> I tried to find a way to reproduce the crash, playing with timedatectl to loop back just before midnight every few seconds and forcing the calendars to reload at the same time, with litte success : I could only get a crash on purpose once...
> I think I can use some help :)
