That was about the time that GPU72.com had some server maintenance.

GPU72 had some server downtime yesterday (time zone dependent). The P-1 in my example did not start a new exponent at about that same time. Maybe it was not able to get new work.

First let me say everything seems to be running fine as far as I can tell. I'm doing some P-1 only (darn usage limits) Anyway, I finished one exponent and went on to the next and when the next one started I got this. Don't know if it means anything substantial or not but thought I would let it be known.
Code:
20200429_203344 ( 6:39): [Comm thread Apr 29 20:33] PrimeNet error 7: Invalid parameter 

20200429_203344 ( 6:39): [Comm thread Apr 29 20:33] parameter c: Invalid string length: 0

Thanks for the report. That looks like a comms error between the mprime client and either the GPU72 and/or Primenet server(s). This happens sometimes.

There is some resiliency there, so the run /should/ be cleanly sent. Does it appear in your completed list?

The one previous to this happening does. That error message came up AFTER the next payload way fetched.
