        You need to recompile squid with a higher maximum swap file number.
This can be achieved by editing store.c and looking for where the #define
for MAX_SWAP_FILE is. Just increase the amount the shift is done by. The
default is 1<<21 or only 2M swap files, which amounts to about 33Gb of disk
space. Once hit get over that you need to increase MAX_SWAP_FILE.

        Cheers,
