The error has happened again.

I looked at the PCC Errlog,
There are two types of errors listed,
1) #10054 "The virtual circuit was reset by the remote side executing a 'hard' .... close........." This one seems to coincide with the "Error initialization ....." Requiring me to restart and log in to PCC.
2) #10053 "An established connection was aborted by the software in your host machine,
possibly due to a data transmission timeout or protocol error ......" This error seems to coincide with the successful credit card transactions, and apparently is not a problem ?
Thanks
