[squid-users] cache_peer problem

hello @all
when my squid is requesting at its "cache_peer" the "cache_peer" is
accepting the first request and at the second request nothing anymore.
The log is saying than that the "cache_peer" is dead. If i restart the
squid ths same again just one request is comming trough and that's it.
Here the log:
here the squid is started
