Ok. It makes sense that the ~200 messages all at once could have happend at the restart. SNFClient will keep trying for 30-90 seconds before it gives up and spits out it's error file. That's where your delays are coming from. SNF itself was clocking only about 100-800ms for all of the scans.

The error result you report is exactly the one sent by SNF -- that it was unable to open the file.

I am very sure this is resource related -- your scans should not be taking the amount of time they are and I suspect most of that time is eaten up trying to get to the files. The occasional errors of the same time are a good hint that IO is to blame.

The new spam that we've seen often includes large messages -- so that's going to put a higher load on IO resources -- I'll bet that the increased volume and large message sizes are pushing IO over the edge or at least very close to it.

Best,
