SQUID problem

[Radek Andrs]

Ahoj vsichni,

setkal jste se nekdo uz s timhle problemem (a neprisli jste na neco jak to
omezit ci odstranit ?):

Cas od casu se SQUID jakoby zasekne a prestane odpovidat na pozadavky.
Chyba je nekde v jeho zpusobu jakym zachazi s DNS.

Dokonce  tom pisou i na SQUID strankach (ale nic povzbudiveho - viz nize):
---------------------------------------
Problems with internal DNS code
platforms Solaris 7, gcc 2.95.2 19991024 and Sun Workshop compilers.
Debian GNU/Linux 2.1, gcc 2.7.2.3, kernel 2.0.38
versions 2.3.STABLE2
synopsis For some reason, squid will periodically decide that it can't
resolve hostnames. It doesn't do this consistently and when it does, it does
seem to be at time when load is lower than normal - for example, the cache
will behave itself during weekdays, but during evenings and weekends, when
the load on the cache drops, DNS resolution problems start.
We seem to be getting errors of either (from yesterday)
Server Failure: The name server was unable to process this query.
or
No Address records.
http://news.bbc.co.uk/ seems to be a common error case.

status Reported, waiting for more details
----------------------------------------

najnovejsi 2.4.DEVEL2)

Jeste jsem zjistil, ze named pak hazi takovehle hlasky:
