This problem is well known. Just search the list.

mmcache stores binary data in shared memory and on disk. After restart / 
reload it seems that the disk cache is corrupted somehow.

You have two options.

1. Disable caching to disk. mmcache option shm_only. Bad, because then scripts 
which are too big for SHM caching are not cached at all.

2. Keep the config and change the start/stop script to clear the mmcache 
caching directory at every start / restart. Working for me since months 
without problems.

Besides mmcache, I only can recommend eaccelerator, which is the project which 
continues mmcache development.

@Stefan Gattenhauer:
I would really suggest that you do not mention the shm_only option without 
telling the possible backdraw stated above and without mentioning the 
alternative I mentioned above.

Best,
