Comment 0 for bug 1781576

Hello, I have found Apache dying after Logrotate runs. First this happened on the 02th July, then on a different server (but practically identical) on the 07th July and again on server 2 today (13th July).

I have attached the crash report from Apache.

Below is an extract from the error logs and a backtrace ran against the coredump:
