More than 100 items having missing data for more than 10 minutes

Hello,

We had a major issue - Dell server midplane failed and all VMs crashed very ungracefully - several times the disk array was just disconnected.
As a result, when we recovered the systems, there are items stuck in Zabbix proxies that won't clear out.
Is there any chance to clear the queue? Other than rebuild the proxies or Zabbix itself? Admittedly, proxies were not backed up.

Thanks for help!

It can take awhile to catch up, but we had problems with 3.4 from 3.4.5 thru 3.4.7 where items are slow syncing to history. We are a little over 4000 NVPS, if "ps aux | grep sync" shows all syncers busy abut at a slow rate, you may have this problem.

Hi,

I am experiencing the same problem where items for all my hosts in the zabbix server stopped being polled. What could be the problem?
