The switch is from APR to JIO. SSL practically doesn't get used. Almost all pages served are jsp or java, very little static files are served and keep-alive is on.
where peak busy-threads used to be ~50 with APR, now it has become ~200 with JIO. Here are the connector definitions for reference (no executor is used): - APR: <Connector port="80" protocol="org.apache.coyote.http11.Http11AprProtocol" compression="1024" keepAliveTimeout="60000" maxKeepAliveRequests="-1" enableLookups="false" redirectPort="443" maxThreads="150" pollerSize="32768" /> - JIO: <Connector port="80" protocol="org.apache.coyote.http11.Http11Protocol" compression="1024" connectionTimeout="10000" keepAliveTimeout="60000" maxKeepAliveRequests="-1" enableLookups="false" redirectPort="443" maxThreads="720"/> On Fri, 2010-03-05 at 19:13 +0100, Caldarale, Charles R wrote: > > From: Christopher Schultz [mailto:ch...@christopherschultz.net] > > Subject: Re: jvm exits without trace > > > > I thought he said he was using APR, not NIO. > > He was, but IIRC, switched away from it to see if that would affect the > outages.
