Hi Raj,

I just realized I did not answer your original question. That huge pause, I
would expect it would be garbage collection. You likely have lots of memory
in your tomcat box and it is taking a long time to garbage collect it.

If you switch to the incremental garbage collector (-Xincgc), you will not
see that huge pause (if that is  the cause), but the trade off will be lower
overall throughput as the GC runs more often.

Subject: Problem with AJP 1.3 Connector


Hi,

I have six Apache webservers in my front-end and one Tomcat server in my
backend. All these 6 apache servers connect to single tomcat engine using
AJP Connector.

Each apache server is configured in such a way that it accepts 150 client
requests at a time. In tomcat server.xml, the AJP min processors is set to
120 and max processors to 1200.
Now the problem is, sometimes the users dont get any response on the website
for 15-20 mins. All the requests dont have any response. But after sometime
again everything is normal. So the assumption I take is apache is sending
requests to tomcat, but because of the huge load, tomcat might be queueing
the requests.

So can any please say me what should be the parameters I set for tomcat to
remove this problem ??? This is a very urgent production problem so any
immediate help would be highly appreciated.

Thanks & Regards,

..Raj
