[cpzengel]

Hi Guys,

we still have the massive Load we cant solve

Mysql heavy Duty

DELETE syncedmessages.* FROM syncedmessages LEFT JOIN syncs ON syncs.id = syncedmessages.sync_id WHERE syncs.id IS NULL

It´s 280 Users running Webapp and Z-Push

WebApp:
5.2.0.0-1+169.1

Kopano Core:
8.7.24

Z-Push: 2.6.2+0-0

The Problem should be solved sice 8.7.24, but its not here

Please advice
