First of all, thank you for your prompt reply. After using synchronous="false" in cxf bc consumer endpoint, looks like it is working fine (client got the time out if the request taking too long, but still the server is not frozen after 32 concurrent threads).
Then I wanted to understand this property, but couldn't find it in the list of cxf bc consumer endpoint attributes (http://servicemix.apache.org/servicemix-cxf-bc.html) Is there any other new documentation that I should look for ? I just wanted to understand the difference of setting that to false. (Finally after looking inside the code, found that it's is calling DeliveryChannel.sendSync() or DeliveryChannel.send() based on this value, but both methods, java doc says that, they supports concurrent invocation for multi-threaded environments. I am little bit confused here) With reference to the other solution you suggested (setting the jetty thread pool size), before posting my initial question here, I actually tried it with no success. Then only I decided to post it again. This is my cxf bc xbean.xml (when I tried to set the jetty thread pool size). ======================================================== <beans xmlns="http://www.springframework.org/schema/beans"; xmlns:cxfbc="http://servicemix.apache.org/cxfbc/1.0"; xmlns:http="http://cxf.apache.org/transports/http/configuration"; xmlns:httpj="http://cxf.apache.org/transports/http-jetty/configuration"; xmlns:fraudcontrol="http://com.nps.servicemix.services/fraudcontrol/"; xmlns:xsi="http://http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://servicemix.apache.org/cxfbc/1.0 http://servicemix.apache.org/schema/servicemix-cxfbc-3.2.2.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://cxf.apache.org/transports/http/configuration http://cxf.apache.org/schemas/configuration/http-conf.xsd http://cxf.apache.org/transports/http-jetty/configuration http://cxf.apache.org/schemas/configuration/http-jetty.xsd";> <cxfbc:consumer wsdl="classpath:FraudControl.wsdl" targetService="fraudcontrol:FraudControlService" targetInterface="fraudcontrol:FraudControl" /> <httpj:engine-factory bus="cxf"> <httpj:engine port="8092"> <httpj:threadingParameters minThreads="1" maxThreads="12" /> <httpj:connector> <bean class="org.mortbay.jetty.nio.SelectChannelConnector"> <property name = "port" value="8092" /> <property name="threadPool"> <bean class="org.mortbay.thread.BoundedThreadPool"/> </property> </bean> </httpj:connector> </httpj:engine> </httpj:engine-factory> </beans> ============================ But I got the following error with that ========================= <stack-trace><
