Thanks for the reply. I am using SOAP::Lite under mod_perl, not CGI. Ive tried altering my SOAP requests but I still get this intermittant problem. I have used your SOAP requests as models and the problem continues. I have further updated my SOAP requests to include a full = URI as per the SOAP spec. I just tried it now and made two requests. The first failed...the = second worked. As you suggested I set 'MaxClients 1' in my httpd.conf. =20 Heres the trace... ------------------ HTTP-Trace-Version: 1.0 Generator: Charles/3.0.2 Method: POST Protocol-Version: HTTP/1.1 Protocol: http Host: echo.localhost File: /soap Remote-Address: 172.30.6.60 Client-Address: 127.0.0.1 Start-Time: 2007-05-08T10:46:56.250+01:00 Response-Time: 2007-05-08T10:46:56.471+01:00 End-Time: 2007-05-08T10:46:56.481+01:00 Request-Header-Size: 668 Response-Header-Size: 248 Request-Body-Size: 454 Response-Body-Size: 576 Request-Body-Decoded: false Response-Body-Decoded: false Request-Header:<<--EOF-1178618598002- POST /soap HTTP/1.1 Host: echo.localhost User-Agent: Mozilla/5.0 (Windows;

Please provide your SOAP client calls and/or SOMs. In particular, the SOAPAction header. It is impossible to verify without being able to reproduce.
