[squid-users] SQUID: cache_dir filling up and squid imploding

Hi all,
We have a squid running for quite a few years and with the increase of
traffic we noticed a bit of I/O hammering on the squid server (local
disks).
For some testing, I've made a small 1.2GB tmpfs and pointed cache_dir
to it so that our cache would be in the 'ramdrive'.
This did help a lot with I/O, but squid eventually once in a while
implodes when it fills 1.2GB of the ramdrive (cache_dir is configured
for 1G, leaving 200MB free).
This is on a CentOS based system:
[####EDIT#### squid]# rpm -qi squid

relocatable)

Description :
Anyone can help? Imagine I want to keep working on a ramdrive with
1.5G. How much can I get cache_dir configured with a safe margin so it
doesnt fill the space?
Any options I should look over again which might help me diagnose if it
happens again?
Kindest Regards,
NMM
