Hi, We have an application that integrates with squid over ICAP - a java based application. We're finding that the java application has very long garbage collection pauses at times (20+ seconds), where the application becomes completely unresponsive.
We have squid configured to use this application as an essential service, with a timeout for 20 seconds. If the application goes into a GC pause, squid can throw an 'essential ICAP service is down' error. The problem is most of the time it doesn't. It only happens maybe 20% of the time - even though some of the pauses are 25 seconds+. Squid is setup to do an 'OPTIONS' request on the java application every second, so I don't understand why it doesn't detect the java application becoming unresponsive. Any feedback much appreciated.
