Re: Coyote HTTP Connecto memory leak with repeated sumultaneous requests fro

Is there any Coyote HTTP Connector setting like timeout to release this kind
of memory. I am using the IE for testing.

Thanks and Regards,
Bhakta

Re: Coyote HTTP Connecto memory leak with repeated sumultaneous requests fro

Sorry for the top post, but no choice with this $%* Notes e-mail client...
Normally, a browser will try to pipeline requests, which means that 
multiple requests are sent over a single connection without waiting for 
responses.  The responses are, however, required to be returned in the 
same order as the requests.  There are two possibilities I see here: 
either 1) the buffering of these separate requests and/or responses is not 
release properly, or 2) your browser is never fully consuming some 
response off the socket, which leads to retention of the queued responses. 


I would suggest you use a packet capture tool like Ethereal (Open Source) 
to see what the interaction is at that level while recreating this 
problem.

sumultaneous requests fro




I am tomcat 4.1.29 as standalone web server with the CoyoteConnector and 
the
configuration as follows







I noticed the memory leak if there are multiple repeated requests from 
same
browser simultaneously without waiting for response. It is keep 
accumulating
the memory and not releasing for eve r(even after the session timeout).



Similar test case with 100 requests ( ran to completion) one after other 
is
not leaking any memory.



We are using Synchronized Token while submitting the forms but we are not
using the same in other cases like HTTP/GET.



I ran the tomcat with JProfiler and noticed that the memory leak is 
pointing
to org.apache.coyote.http11.InternalInputBuffer.



I used the Tomcat 4.1.31 and still has same problem.



Any help is greatly appreciated.



Thanks and Regards,

Bhakta
