 +======Socket Error 10055 - No Buffer Space Available======
 +Error 10055 means that Windows has run out of TCP/IP socket buffers because too many connections are open at once.
 +Things to check if this happens are:
 +  * Is there any other TCP/IP software running on the same PC as VPOP3 - eg a proxy server
 +  * Use a virus scanner to check for malware, as some malware is badly written and will use a lot of connections
 +  * Use a program such as [[http://​​en-us/​sysinternals/​bb897437|TCPView]] or [[http://​​en-us/​library/​ff961504(v=ws.10).aspx|NETSTAT]] (with the -b parameter) to see which programs have connections open
 +Current versions of Windows can support many thousands of IP connections at once. Server versions can support more than desktop versions if you have a busy server, so it is unlikely that VPOP3 on its own will deplete the socket buffers, and the problem is usually some other software.
