It's not a BI change. As @algertc said, the ALPR Database project has been updated to accept a larger payload.Hmmm.... I just updated to BI 5.9.9.21 and the no stream errors are still there.
I was NOT getting the 12002 error, so maybe your issue is different. Try checking the log (penultimate tab on the left, just above the configure/gear icon)
