fFxP Problem in WinXp

[ffxp.user]

I get this error after ffxp has been running for a few hours I'm using WinXp and have 512mb Ram

Connection failed: xxx.xxx.xxx.xxx (10055:No buffer space available)
or Data Socket Error: 10055:No buffer space available

any ideas on whats causing this?

This is generally a winsock error, not limited to ffxp, but any application that uses winsock, and is usually caused by port-scans performed eg. by your ISP looking for undesirable services. The only real solution is to reboot the machine.
