>          Components: core/transport

>         Environment: All
>            Reporter: Matt Mason

> This problem affects at least 1.5.0 and 1.6.0.  I haven't checked any earlier versions.
> When viewing the wsdl via services/ServiceName?wsdl
> the wsdl is opened with a call to fopen and the result assigned to a local FILE* variable.
 However there is no corresponding call to fclose.
> We have a monitoring script that periodically requests the wsdl to check that the service
is available.
> The process (currently) has a limit of 1024 open file handles, eventually this leak causes
that number to be exceeded.
> The client library we use to connect to the service also requests the wsdl file when
connecting to the service.
> With reference to the code in the 1.6.0 release, here is the 1 liner to plug the leak.
