I tried with Tomcat6 compiled from trunk revision 532271 and two browsers sending the requests.
Unfortunately it is not that easy for me to put the dump on a public web server. Instead, I had a look at the dump myself. First I ran Tomcat with a single connector with attribute maxThreads=20, and started it with -Xmx10m. In the dump I saw 103 instances of class org.apache.coyote.http11.Http11AprProcessor and the same number of all the attached objects like Request, Response ... I tried again with -Xmx20m (same configuration otherwise) and saw 249 instances of class org.apache.coyote.http11.Http11AprProcessor. Thus, let us guess that the number of instances increases if I spend more memory. As far as I could see the ConcurrentLinkedQueue<Http11AprProcessor> recycledProcessors contains a single entry. But the RequestGroupInfo holds 249 instances of org.apache.coyote.RequestInfo: Instance of java.util.ArrayList (12 bytes) Class: class java.util.ArrayList Instance data members: elementData (L) : Instance of [Ljava.lang.Object;@0x27e379b0 (1204 bytes) modCount (I) : 249 size (I) : 249 Object allocated from: References to this object: [EMAIL PROTECTED] (44 bytes) : field processors -----Original Message----- From: Filip Hanik - Dev Lists [mailto:[EMAIL PROTECTED] Sent: Tuesday, April 24, 2007 11:47 PM To: Tomcat Users List Subject: Re: Memory Leak with Comet Why don't you enable -XX:+HeapDumpOnOutOfMemoryError and send us a link where we can download the HPROF files that get generated. Also send us your config as well when you get the error Filip --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
