Server crash every day

I contacted support as a servehoster several days ago, but unfortunately no response came yet.
One of our instances crashes every day in the evening. It is not clear where the problem is. All other instances run reliably and without problems.
I sent the server dumps to support. The new dump every day. Unfortunately no feedback came yet.
Does anyone have any idea why?
Does anyone have the same experience?
There are over 120 TS3 servers running on the instance, which are down until we accidentally notice it or customers contact us.
Iā€™m grateful for a tip

I can see the ticket but can not read the crash dumps and logs are not provided.
So from that position i can not help you.

Please attach the logs to the ticket as requested from the support.
