[fabianb]

Hallo Zusammen,
seit dem letzten update, also Sonntag, stürzt die Instanz admin.0 in regelmäßigen Abständen ab.

2019-07-02 12:09:58.571  - info: admin.0 Unsubscribe from all states, except system's, because over 3 seconds the number of events is over 200 (in last second 0)

CPUs           : 2
RAM            : 4.8 GB 
Node.js        : v8.11.3
Disk size      : 14.2 GiB
Disk free      : 8.5 GiB
adapters count : 281
NPM            : v6.8.0

Irgendeine Idee?
