Internal events are being generated at the rate of 200-300K per hour causing DB performance particularly on subsequent housekeeping.
This was occurring at 3.4.3, we upgraded to 3.4.6, then downgraded to 3.4.4.
Multiple triggers from the same or similar prototype are involved, sample problem expression:
{csg5k1:net.if.in.errors[ifInErrors.436744192].avg(5m)}>{$IF_ERRORS_WARN:"Ethernet2/4"}
or {csg5k1:net.if.out.errors[ifOutErrors.436744192].avg(5m)}>{$IF_ERRORS_WARN:"Ethernet2/4"}
Some of these items are "no longer discoverable" but seem to have current data.

I haven't found any corresponding messages or internal item events.
Volume of events is causing total zabbix failure.
