Is there anything that you guys can suggest I do around the cache? Should I try a different store type? A different filesystem type perhaps? If your store has a configuration knob that effectively limits disk writing rate, then use it to limit that rate to avoid overflowing the queue. You can

Hi all In my environment I have two Squid clusters that comprise of 4 VM's each, load balanced over a F5 LB. I will refer to them as cluster A (client facing) and cluster B(edge proxies). Depending on the destination, the traffic is routed from cluster A via ISP 1 or to cluster B via ISP 2. I
