I've pulled the Log, and there are many hundreds of these lines with a date and time (going back a couple of weeks):
[6433][1][FATAL] No Value for arguments for PMSE method closeFlow
[5592][1][FATAL] No Value for arguments for PMSE method closeFlow
[5925][1][FATAL] No Value for arguments for PMSE method closeFlow
[9873][1][FATAL] No Value for arguments for PMSE method closeFlow
Any insight of where I should be looking for the issue?
