Hi List,
having run without problems for weeks, from one moment to the following my
Debian 7 based Squid 3.1.20 didn't provide WWW pages anymore to the
connected clients. All networking stuff, included DNS resolution still
worked without problems (ping, nslookup, tracert/traceroute), but the web
browsers didn't show the requested pages (showed error page "Connection not
possible").
The cache is sized 20GB on a seperate disk partition - and it has been
completely full. Having deleted the cached objects and restarted the squid3
service, it built the cache structure again and worked again without
problems.
So, what's wrong with the replacement of cached objects?
This is what it looks like:

Is it a rights problem? Should the contents belong to root:root instead of
proxy:proxy?
AFAIK the replacement function of cached objects doesn't have to be
configured - it is an implemented function by default, isn't it?
The cache replacement policy ca be configured, but its function is to
determine HOW or in which ORDER the objects have to be replaced:
http://www.squid-cache.org/Doc/config/cache_replacement_policy/ ; BTW: mine
is LFUDA. Is something wrong with it in Squid3?
Ideas?
Thanks in advance!
Regards,
Bob
