Hi,
I am new on the list. I got a similar problem.

If I put "sendToAdress" transactions to bitcoind, it will accept between 1
and 3 transactions per minute, depending on the underlying machine.
If I try to send one transaction every 20 seconds or less, bitcoind stops
responding to RPC calls.

Does anybody know of any solution / fix / workaround for this?

Thanks in advance.
