C# on win calling web service apache on unix - runs out of ports

Hi,

I hope someone can follow all this because I am having a problem with it all, so please feel free up insert correct terminology and correct concepts I have got wrong. Ok - here goes:

I have an application that sends 'jobs' to a linux machine via an apache web service. It's pretty slow so I took some time to speed it up but I'm now hitting the wall with regards to the linux machines free ports. There are <30k ports available with a keep_alive time of 2 hours. I am looking onto changing this to increase available ports and reducing the keep_alive time but there are other machines that require the keep alive time to be longer than I had hoped. not quite 2 hours but long enough that I may well hit the wall in the future.

The question at it's core is 'What do I do to solve this?', but hopefully I have broken that down with these two questions:
1: Is there a way keep using a single port for each subsequent request?. Or...
2: Is there a way that I can tell the linux machine to close the port when I'm done with it?

I have limited access to the linux machine and limited scope to change it's behavour, but it is do-able if that would be the only (or very much best) solution.

I don't really know what search terms to look for so I haven't been able to find much in the way of online articles so any help there would be very much appreciated.

Thanks

PS: I spoke to another techie here and he says I should mention that the webservice is defined in a wsdl that specifies a port:

  <wsdl:binding name="JobservBinding" type="tns:JobservPort">
    <soap:binding transport="http://schemas.xmlsoap.org/soap/http" style="rpc" />
    <wsdl:operation name="addxec">
<!--etc...--!>

But this again confuses me :?


PS exact error
"Only one usage of each socket address (protocol/network address/port)\r\nis normally permitted 10.<ip of="" the="" linux="" server="">:80"
