Have a fairly recent install of NPM. Using just preconfigured alerts - mostly. Reboot the server - everything is fine for while. Alerts write to event list and/or get email as configured.
after a while this stops. no idea why. reboot the machine - all queued up events come flying in. works for a little while then stops.
no indication of any issue etc. thought it might be performance related because it's on an older machine. reinstalled to a much new, faster machine - same thing. new install, new database, etc.
any ideas? v.10.1
