problems with 1.1.1

Hi there

I am having a couple of problems with squid 1.1.1:
I have been running this version for a few weeks without hassles on
a linux machine, kernel 2.0.24

Yesterday our second cache (we load balance between two cache machines
just hung up (stopped accepting connections). An strace showed:

read(898, "\345\360\3433\34!\226\267]h\362\227"..., 65535) = 1460
gettimeofday({852886178, 207491}, NULL) = 0
gettimeofday({852886178, 207842}, NULL) = 0

over and over again. (ie Select didn't seem to show that there was any activity on any open filehandles)

with a few
unlink("/usr/local/squid/cache/04/0B/0004C0B4") = 0
unlink("/usr/local/squid/cache/09/71/00068719") = 0
unlink("/usr/local/squid/cache/06/F1/00063F16") = 0
unlink("/usr/local/squid/cache/0A/57/0005557A") = 0
unlink("/usr/local/squid/cache/06/16/00058166") = 0
unlink("/usr/local/squid/cache/0C/30/0006330C") = 0
unlink("/usr/local/squid/cache/02/72/0004F722") = 0
unlink("/usr/local/squid/cache/0B/2D/000572DB") = 0
gettimeofday({852887256, 118399}, NULL) = 0

here and there

Of course this may be related to my patch to get linux to do more that 256
filehandles. Stangely our other squid then started acting up, and I rebooted
both the machines.

The other thing is:

Cache 1 runs squid 1.0.18

Clearly squid 1.1 is getting the page from the real site every time, with
the logs showing
852973763.314   3115 196.23.0.84 TCP_REFRESH_MISS/200 4716 GET http://www.vodacom.co.za/ - DIRECT/www.vodacom.co.za text/html
But if I look at the headers there doesn't seem to be any "meta" info... and
cache manager shows:
17.http://www.vodacom.co.za/
      Verified 27Y ago, Used 3s ago, Modified 19s ago, Expires 27Y ago,

Any ideas?
