Hi Books4Me. Thanks for the feedback. Someone else reported seeing
this error on Friday the 28th as well. Our host didn't indicate any
down time during this period and it appeared to resolve on it's own.
We will be increasing the RAM in the servers to ensure they don't max
out again. Apologies for the trouble and thanks for writing to let us
know about this issue. As the service has become more popular we've
experienced a few growing pains.
