[squid-users] Detected DEAD parent

Hi,

These last times, I have a lot of these messages in squid's cache.log :
2004/08/04 10:19:40| Detected REVIVED Sibling: sibling2/8080/3130
2004/08/04 10:19:40| Detected REVIVED Parent: parent2/8080/3130
2004/08/04 10:19:40| Detected REVIVED Parent: parent1/8080/3130
2004/08/04 10:19:40| Detected REVIVED Sibling: sibling1/8080/3130
2004/08/04 10:19:45| Detected DEAD Sibling: sibling1/8080/3130
2004/08/04 10:19:51| Detected REVIVED Sibling: sibling1/8080/3130
2004/08/04 10:21:20| Detected DEAD Sibling: sibling2/8080/3130
2004/08/04 10:21:20| Detected DEAD Sibling: sibling1/8080/3130
2004/08/04 10:21:20| Detected REVIVED Sibling: parent2/8080/3130
2004/08/04 10:21:20| Detected REVIVED Sibling: sibling1/8080/3130
2004/08/04 10:21:34| Detected DEAD Sibling: sibling1/8080/3130
2004/08/04 10:21:46| Detected REVIVED Sibling: sibling1/8080/3130
2004/08/04 10:22:50| Detected DEAD Parent: parent1/8080/3130
2004/08/04 10:23:12| TCP connection to parent1/8080 failed
2004/08/04 10:23:12| TCP connection to parent1/8080 failed
2004/08/04 10:23:12| TCP connection to parent1/8080 failed
2004/08/04 10:23:12| TCP connection to parent2/8080 failed

I have a lot of those "detected DEAD parent/sibling" in the logs. It happens
very frequently (almost every 5-10 minutes) and it results, for the user, in
the message ERR_CANNOT_FORWARD.

My conf is the following :
cache_peer sibling1 sibling 8080 3130 proxy-only
cache_peer sibling2 sibling 8080 3130 proxy-only
cache_peer parent1 parent 8080 3130 weight=90
cache_peer parent2 parent 8080 3130 weight=50
icp_query_timeout 3000
maximum_icp_query_timeout 3000

I have already increased the icp_query_timeout and maximum_icp_query_timeout
parameters, but with no success. This problem has appeared recently with
no changes on squid boxes. What could be the reason of it? The network?

Thx in advance.
