Three out of seven ACE calculations failed with this error:
[-10735] PINET: Session Manager Transaction List Full.: Stack Trace = at OSIsoft.AF.PI.PIException.ConvertAndThrowException(PIServer piServer, Exception ex, String message)
The calculation inserted -999999 which is the default value for the tag. I looked in to PI server/ACE/Windows logs and couldn't find anything out of ordinary. Interestingly the error messages stopped after one hour.
Other ACE calculations continued to populate values during this period.
Any suggestions for what caused this error and how ?
