So you should probably split your cache over two directories. Stop Squid cd /path/to/cache mkdir 1 mkdir 2 mv ??* 1 then change squid.conf to have /path/to/cache/1 and /path/to/cache/2 both listed with a cache_dir directive each. To migrate smoothly configure 1 to it's current size, 2 to the remaining size. Then over the next days gradually adjust them until there is balance.. > In addition there is 100% CPU for some time before the crash.

Very large bitmaps is not efficient. Regards Henrik
