flowd_aggregate crash

[DonConto]

Netflow crashes after a minute or two. Not sure, but the problem occurs after adding an additional interface via "Interfaces: Assignments" for ovpns1. Maybe there is a 'corpse' in a config file now?!

Output:

I tried to reset and repair via GUI and also a rm of the sqlite files. But nothing helped.

@DonConto 01d8fb2 should catch these errors.

To test, use the opnsense-patch 01d8fb2 on a console (and restart the flowd_aggregate service).

Netflow service is now stable. Thank you for your support.

@DonConto thanks for letting us know!

This worked for me too. 👍
