RE: issue with htcp support on squid

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I ran into this as well when I upgraded from 2.6 to 3.0 (stable10) and
tried converting from icp to htcp in the process.  Squid would start up,
go for a little while, and then die in less than 2 minutes.  I resolved
this by adding 'no-query' to my cache_peer sibling statements (in
effect, turning off intercache communication).  I would like to know how
best to re-enable sibling communication, and whether or not I'm in the
same boat here (waiting for a bug fix).

relevant portion of config...

icp_port 0
htcp_port 4827
icp_query_timeout 500
cache_peer x.x.x.1 sibling 80 4827 htcp proxy-only no-query
cache_peer x.x.x.2 sibling 80 4827 htcp proxy-only no-query
cache_peer x.x.x.3 sibling 80 4827 htcp proxy-only no-query
acl siblings src x.x.x.1 x.x.x.2 x.x.x.3
http_access allow siblings
htcp_access allow siblings
htcp_access deny all

cache.log from that time - notice the "neighborsUdpPing: There is no ICP
socket!" towards the end...that's where Squid would die, and try to
revive itself, but never really get airborne

Please file a bug. HTCP operation is not supposed to need the ICP
socket.
