That depends on what the partition is filling up with.

If its cache objects not being erased, its probably bug 3553. High
traffic speed is the bug trigger. There is a fix in the latest 3.5
snapshot already if its urgent - and will be in the 3.5.8 I'm currently
preparing for release (ETA within 24 hrs).


For completeness; if swap.state or netdb journals are growing huge and
filling up the extra partition space. Then its probably just "squid -k
rotate" not being used often enough for the traffic volume. Regular, but
not too frequent, rotation is good for Squids overall health and clears
up file based outputs in all sorts of areas.

Thank you Amos. I will look out for the 3.5.8 release and manage the situation in the mean time.

I upgraded to 3.5.8 on Friday 04/09 and so far it has been behaving well with the cache directories dropping to 59%. Thanks Amos.
