Asankha C. Perera commented on SYNAPSE-452: ------------------------------------------- I have fixed this already.. and will checkin the code shortly after a bit of more testing > low load: ERROR ClientHandler Unexpected HTTP protocol error: Request already > submitted > --------------------------------------------------------------------------------------- > > Key: SYNAPSE-452 > URL: https://issues.apache.org/jira/browse/SYNAPSE-452 > Project: Synapse > Issue Type: Bug > Components: Transports > Affects Versions: 1.2 > Environment: found on wso2-esb 1.7.1 (having synapse 1.2) running on > debian. XEN vm's running on Intel HW. > The back-end is a spring webapp (using cxf, using commons-httpclient) > We run the backend on the same VM as the ESB. > Reporter: harm verhagen > Assignee: Asankha C. Perera > > I'm seen http connection related exceptions when under _very_ low load. > what do I do: > I proxy a soap interface of a backend, using wso2. > I issue a soap command using www.soapui.org. > After 1,2,3 commands (issue manually) the bus gives internal excpetions. > what do I get: > from ESB logging. > 2008-09-16 15:33:29,157 [127.0.0.1-vloeki_v01] [HttpServerWorker-9] ERROR > ClientHandler Unexpected HTTP protocol error: Request already submitted > org.apache.http.HttpException: Request already submitted > at > org.apache.http.impl.nio.DefaultNHttpClientConnection.submitRequest(DefaultNHttpClientConnection.java:203) > reference: > more details & logs at: > http://wso2.org/mailarchive/esb-java-user/2008-September/000812.html > workaround: > When not running the ESB and the backend on the same machine, (or better > said, when routing the traffic between ESB and backend trough an other > machine). The problem went away.. > see http://wso2.org/mailarchive/esb-java-user/2008-September/000840.html. > This obviously isn't a real fix. > This issue might be related to: > https://issues.apache.org/jira/browse/SYNAPSE-344 > https://issues.apache.org/jira/browse/SYNAPSE-341 > https://issues.apache.org/jira/browse/HTTPCORE-170 > however, I'm seeing this under very low loads, very reproducable.
