2.4.DEVEL2 - Storage LRU Expiration Age

Hi there

I don't know if this is a bug...

Before having patched 2.4.DEVEL2, "Storage LRU Expiration Age"
was nearly zero and CPU use was high; after the patch that value stucked
at 365.00 days. Now, I know this isn't possible because
I changed from the non-patched to the patched version a few
days ago and didn't empty the cache, so squid should start
calculating a new value in a few minutes/hours.

Other than this little problem, this version is working ok with diskd...

Maybe squid doesn't yet do the arithmetic rigth with diskd?
Does anyone have the same problem?

Thanks,
JP
