[SQU] cache_dir problem

Hi all,
I have configured 3 separate cache directories by means of these tags at squid.config file:

cache_swap_low 95
cache_swap_high 95

cache_dir ufs /var3/squid 17500 32 256
cache_dir ufs /var/squid 16384 32 256
cache_dir ufs /var2/squid 17000 32 256

and this is the report of filesystem disk space usage ( df ) :

Filesystem 1k-blocks Used Available Use% Mounted on
/dev/hda1 561292 394860 137920 74% /
/dev/sda3 576504 354380 192840 65% /log
/dev/sda5 16387643 13470264 2064132 87% /var
/dev/hda5 17196092 14058808 2263752 86% /var2
/dev/sdb5 17646672 2450936 14299316 15% /var3

but cache_swap_low and cache_swap_high don't function correctly at /var2. /var2 reaches to its 100% of capacity and after that squid doesn't function correctly and issues these messages continually:

2000/08/29 00:01:59| diskHandleWrite: FD 8: disk write error: (28) No space left
 on device
FATAL: Write failure -- check your disk space and cache.log
 

Does anybody knows what is wrong with my configuration?
Thanks in advance
