cache problems

Hi all !

This morning, my squid was down, the problem: cache's filesystem full:

/dev/sdb1 4048136 3838690 0 100% /cache

the error in cache.log:

1999/08/09 01:15:27| diskHandleWrite: FD 296: disk write error: (28) No

FATAL: Write failure -- check your disk space and cache.log
Squid Cache (Version 2.2.STABLE1): Terminated abnormally.

Well, the squid.conf configuration:

cache_dir /cache 3500 16 256

as you see, my filesystem has 4 GB and my only cache_dir 3.5GB, the
configuration it worked very well by almost a month, is something rare
that it passes this problem now. In order to create space in filesystem,
I erased swap.state and I created it again, cache_dir was modified
3.00Gb. I am restarting squid but the problem persists, the disc space
of filesystem (/cache) is increased, This information appears in
cachemgr.cgi moments before squid falls

what's incorrect? what this happening in my squid? (squid 2.2 Stable1)
if you need more information, only tell me.

Thanks in advance.
