mmcache is running perfectly for several hours then
suddenly every httpd-process keeps on crashing with a
segmentation fault. This happens almost every day. I
then have to restart apache.

For testing purposes I have disabled the mmcache on
another identical machine of our cluster an then this
errors are not appearing anymore.

My setup:
- Dual Xeon, 3GB RAM, high load Web/Mysql-Server. Part
of a 3 Server Cluster
- Linux www5 2.4.18-14bigmem
- httpd-2.0.40-11.7
- php-4.2.3 (php is using shared memory functions!)
- mmcache-2.4.2 (compiled from source)

[root@www]# grep mmcache /etc/php.ini
extension="mmcache.so"
mmcache.shm_size="16"
mmcache.cache_dir="/tmp/mmcache"
mmcache.enable="1"
mmcache.optimizer="1"
mmcache.check_mtime="1"
mmcache.debug="0"
mmcache.filter=""
mmcache.shm_max="0"
mmcache.shm_ttl="0"
mmcache.shm_prune_period="0"
mmcache.compress="1"

    I hope the BUG is already fixed.
    Use the latest MMCache release (2.4.5 or 2.4.4).
