Control: found 920235 apache2/2.4.23-5
Control: found 920235 apache2/2.4.37-1
Dear Maintainer,
I tried to find out when this started inside an amd64 qemu VM
and got to these versions:
Stretch/testing of date 2016-10-10 with apache2/2.4.23-4 was ok.
Stretch/testing of date 2016-10-11 with apache2/2.4.23-5 started to fail.
The changelog between those versions mentions
some movement towards systemd.
This is also reproducible in buster/testing of today.
When attaching a debugger to the fold process it repeatedly
receives a signal SIGPIPE, Broken pipe.
Kind regards,
Bernhard
