[squid-users] file too large ?

Hello everybody

I have a heavy problem with my squid 2.3 STABLE 4 running on aix 4.3.3 ml2

For a long period squid was running properly .... but suddenly there is a
heavy problem there.
After a short time (about 30 min) squid gives up responding to request and
replys with a message like:

"file too large"
or
"unable to forward this request at this time"

Architecture is very basic:
Primary Proxy with a Cache Proxy behind.

Debug-log lists:

Remarks:

-> There is definitly no network latency around:
      root@proxy.li.zkb.ch:/var/squid/logs>ping proxy1.zkb.ch
      PING proxy1.zkb.ch (192.168.38.35): 56 data bytes

      64 bytes from 192.168.38.35: icmp_seq=4 ttl=254 time=0 ms

-> Cleaning and rebuilding the cache on both servers did not help

Please help me !
