Just in case there is confusion: Apache 2.2 only allows one of the two rotation
rules, either size or time based, as stated by Eric and Jeff.

Apache 2.4 allows to combine both, i.e. what ever happens first will rotate the
file. One of the small nice things coming with 2.4. Though this ticket was
opened against 2.2, so yes: please fix your config and try again.

If the problem happens again, please see the questions of Jeff in Comment #1.

Isn't the syntax wrong, it has time and size.  So maybe some buffer gets full
trying to write to the piped logger that is never able to init enough to read
lines.

A crash is one thing, a hang is quite another.  Did the error log have anything
about a child process exiting and being restarted?

Secondly, what files (and sizes) had been created or written to by rotatelogs
at the time the hang was detected?

That's right about the syntax; "256M" is taken as the UTC offset.

Benny, please fix the syntax (leave only the rotation time OR the rotation
size) and see how that works.
