Rapuru Sandeep Reddy commented on SM-1541:
------------------------------------------
I have already attached (changepassword-09022008-181250,
changepassword-09022008-180230) thread dump files for your reference.
I identified that the hang mostly occurs in Camel when the inboundExchangeCount
reaches the minimum thread pool size set in servicemix.properties file
(Observed in JConsole for Camel endpoint).
I tried increasing thread pool size to min=30, max=60. And it seems to be
working fine for 1000 users with 200 parallel requests.
Questions:
1. What is the meaning of "servicemix.corePoolSize" and
"servicemix.maximumPoolSize" property value. I do understand that these
specifies the thread pool for servicemix but how is it related to exchange
count ?
2. Why does my operation work some times with default pool configuration ?
3. Can I configure thread pool for each component ? I would probably like to
configure separate thread pool for Camel.

> Client --> Http Consumer SU ----> Bean SU (Message Enricher) --->
> Validation SU (using camel) ----> Routing SU (using camel) ----> Http
> Provider SU ---> Extern Appl
> I am doing load testing having 1000 users with 200 in parallel.
> Servicemix starts processing some requests successfully (it could be any
> number of requests not constant) after that it just hangs.
> Here I am attaching SA for the operation.
> NOTE: 1. In above SA , Http Consumer SU is having authMethod="BASIC"
> 2. So, that requires users-passwords.properties and
> groups.properties files (which i am attaching here) need to integrate with
> servicemix/conf .
