                 Key: AXIS2C-902
                 URL: https://issues.apache.org/jira/browse/AXIS2C-902
             Project: Axis2-C
          Issue Type: Bug
          Components: samples
    Affects Versions: Current (Nightly)
         Environment: Ubuntu 7.10 (Gutsy Gibbon), CURL + libxml2, TCPMon
            Reporter: Senaka Fernando


I have been running echo_blocking_dual in a loop and found out that 
occasionally the simple axis http server segfaults.

My system memory consumption is 575MB/1011MB and swap is 1.5GB/3.8GB. Also note 
that this problem occurred on Ubuntu 7.10 system, with CURL transport. And, I 
ran with the TCPMon utility actively monitoring the payloads.

This is the tail of my axis2.log

Please note that even though the server segfaulted, I got a response "HTTP/1.1 
202 Accepted
" for the last request, the one which made the server segfault. All further 
requests failed as the server is not operational.
