I have been in contact with Travis about this and he told me to increase my scan time from 5mS to 1S on the groups whose scan time was 5mS. I did this and a couple of things happened.
First in the service statisics window my group eff. went upto 66.67% so that is better than it was.
Second I think the time is better but being time is so virtual and not the easiest to measure I can not be sure.
However it still did not fix the problem with the overload errors. I have tried increasing the time more, I have tried started the groups individually, but nothing seems to take away this error. And sometime a group will get multiple of these errors before it goes green and starts working properly. Here is the information presented when I click on the error message.
Error Writing to DB: Overload Resolution Failed because No Public ‘Round’ can be called without a narrowing conversion: 'Public Shared Function Round ('d as Decimal, decimals as integer) as Decimal: Argument matching parameter ‘d’ narrows from Boolean to Decimal: ‘Public Shared Function Round (d as decimal, mode as system.midpoint rounding) as Decimal: Argument matching parameters ‘d’ narrows from Boolean to Decimal: Argument Matching parameters ’ mode’ narrows from Integer to MidPointRounding. And the list goes on for a few other items.
Then I get the group execution aborted. So is this a significant error? What can be done to eliminate it? It does not seem to happen all the time.
