Logcheck devel - Sep 2014 - Bug#761813: logcheck: egrep uses ridiculous amounts of memory

Package: logcheck
Version: 1.3.16
Severity: normal

Lately I've noticed egrep taking enormous amounts of memory when running
logcheck, especially after a reboot. As an example, a 58K patterns file
(with local patterns) combined with a 86K log file made egrep use more
than 1G of ram.

Splitting my local patterns alleviates the problem of course, but that
shouldn't really be necessary for these file sizes.
