[squid-users] WARNING: failed to unpack meta data

Had some strange problems with one of our lvm caches
over the weekend (user's uploaded pages failing to refresh).

The cache crashed on Friday night
Sep 21 20:33:09 squid[1499]: comm_poll: poll failure: (12) Cannot
allocate memory
Sep 21 20:33:09 squid[1499]: Select loop Error. Retry 1

Sep 21 20:33:13 squid[980]: Rebuilding storage in
/var/spool/squid-f(DIRTY)
Sep 21 20:33:13 squid[980]: Rebuilding storage in /var/spool/squid-f-1
(DIRTY)

a little later lots of these:

Sep 21 20:38:15 kernel: eth0: card reports no resources.

The cache was reportedly returning passed-sellby pages on Saturday,
but appears to have righted itself by Sunday [very vague I know,
but nothing in the logs, just vague complaints to go on].

Since then up until now we're getting the following message every few
minutes:

Sep 21 21:24:18 squid[980]: WARNING: failed to unpack meta data

Message comes from storeClientReadHeader() callback.

What exactly does the message mean, and does it have any implications?

Thanks.
