| 5MB.

Noted. This must have been a mistake that I made initially before going
into a cocoon to wait for 2.6STABLE4 to get into FreeBSD ports. At that
moment Squid was giving a complaint realated to disk size.

|
| cache_dir coss /usr/local/squid/squid-coss/c0d2p1 5120 max-size=131072
| cache_dir coss /usr/local/squid/squid-coss/c0d2p2 5120 max-size=1048575

Corrected! Thanks.

| No, they are regular files.

Agreed. I am not sure why I answered otherwise :(

| File permissions seems fine.

| Start with only one coss cache_dir and see what happens.

As recommended, I have started with just one cache_dir

cache_dir coss /usr/local/squid/coss1 5120 max-size=131072

(I recreated the files in a different location)
