I have six workers, and I am trying to monitor the performance of squid
using SNMP.
I get the following type of error quite frequently:
snmpHandleUdp: FD 18 recvfrom: (11) Resource temporarily unavailable
After some Google searching, I gathered that each worker should be on its
own SNMP port, so

I think the wccp2 is set up correctly - I am using tunnel mode. Here is the

Hi
I am struggling with the following error: comm_open: socket failure: (24)
Too many open files

server with 12 cores, 64Gb Ram and 8 x 1Tb disks. The first two are in a
RAID-1, and the balance are managed as aufs caches.
