[squid-users] ICP cache sharing not working after upgrade

After migrating from Squid 2.5.STABLE6 to 2.5.STABLE10 my
two squid servers are not sharing cache anymore.

Both squids are configured in http accelerator mode and one
is a sibling of the other.

In the access_log on 10.0.0.2 I see ICP_QUERIES from the other:

10.0.0.1 - - [14/Jul/2005:15:12:09 +0200] "ICP_QUERY
http://webserver/page.html HTTP/0.0" 0 50 "-" "-" UDP_HIT:NONE

Here the second squid has page.html in cache, but instead of using that,

the first squid has a TCP_MISS and is doing a TIMEOUT_DIRECT.

192.168.1.1 - - [14/Jul/2005:15:15:14 +0200] "GET
http://webserver/page.html HTTP/1.1" 200 104099 "-" "lwp-request/2.06"
TCP_MISS:TIMEOUT_DIRECT

How's that possible ? Has anything changed between STABLE6 and STABLE10
in regard to ICP ?

This is the configuration I'm using for the cache hierarchy:

icp_port 3130
cache_peer 10.0.0.2 sibling 80 3130
acl peers_src src 10.0.0.2 10.0.0.1
acl peers_dst dst 10.0.0.2 10.0.0.1
acl web_access dst webserver
acl web_access_port port 80
cache_peer_access 10.0.0.2 allow web_access
cache_peer_access 10.0.0.2 deny all
http_access allow web_access web_access_port

As for the format of the access_log: I've installed the customlog patch.

Thanks,
