Proxy getting disconnected from Server

[Dileep]

We are using Zabbix 6.0.23 version.

Proxies are getting disconnected for few mins(15-25mins) and again betting back connected, due to this monitoring is getting effected.

Checks we did:

1. Connectivity b/w Proxy and Server there is no flapping - No Issues.
2. Proxy container is UP and Runnnig fine - No Issues
3. CPU and Memory are Normal - No issues

We found this spike in Values waiting to be send item for that proxy:





And when we checked on Server Log we found this error:





Can anyone help on this issues please...

Hi,

If the attached error is always appearing when proxy goes down, it is very likely that issue is between DB server and proxy.

• Are DB server and proxy on the same machine? Maybe there are some timeout settings on either of sides which may be causing this issue - might be worth checking
• You can execute the query manually in the DB to see if the query itself generates issues.

Since the error indicates that connection was lost to the DB server during query execution, I would look for issues on the DB server side.

Hope it helps.
