A quite obvious sign, isn't it.. Not much Squid can do if the OS says
that the filesystem is full other than repeating the fact.

No. This is not a hardware fault. It's more in the range of a OS bug /

Not that unlikely. A default Solaris filesystem with lots of activity of
small files can't be filled very much due to fragmentation even if df
says there is lot's of space available (only block fragments available
== no free blocks, but df reports free fragments as free space..).

If you are using Solaris then you should shange the block allocation to
preserve space instead of time. See tunefs and fs_ufs man pages.

[stop squid]
umount /squid/cache
tunefs -m 0 -o space /squid/cache
mount /cache1
[start squid again]
