Bug#399930: logrotation race condition with exim writing to logs

[Vladislav Kurz]

Package: exim4
Version: 4.72-6+squeeze3
Severity: normal

Hello,

we've got hit by this race condition today. I find it ridiculous that
this bug is not fixed for 6 years, while the fix is trivial. So far only
lame excuses about hypothetical monitoring software that could break
if it cannot find a log file. WTF? Is there such a lame monitoring that
prefers to check the log instead of TCP socket? Or did you mean
something like logcheck? Whatever, running SMTP server is the top
priority. Without that even the monitoring itself is worthless, as it
cannot send any warnings. So please fix this, upload it to unstable,
and we'll see if something else will break.

Regards
Vladislav Kurz
