[squid-users] HELP - "WARNING: Disk space over limit"

Hi everyone,

Software: Squid Cache version 2.5.STABLE3 for i686-pc-linux-gnu, RedHat
Linux v7.3

I've got a strange problem which just started this morning on one of our
squid cache boxes. Squid is logging 'Disk space over limit' warnings.
Samples of these messages are below:

These are being constantly generated.

An edited output from 'df -ah' showing the filesystem that the squid
cache lives in is below:

Filesystem Size Used Avail Use% Mounted on
/dev/sdb1 68G 36G 32G 53% /data

'du -k' is reporting the following as the size of the squid cache
directory:

34830385 ./squid_cache

Squid conf has the following set:

cache_dir aufs /data/squid_cache 40000 60 256

I can't work out why Squid is reporting the warning. The current space
usage of the squid cache is lower that the specified maximum size. The
filesystem the cache lives on has plenty space. Looking at the
warnings, it looks like something internally has overflowed.

Does anyone have any suggestions on how I can fix or further diagnose
this problem?

Regards,
Ken.
