hi  
I am running InfluxDB on a single instance 8 core VM with 1T RAM. The VM is running Linux version 3.10.0-1160.62.1.el7.x86\_64 and InfluxDB v2.3.0+SNAPSHOT.090f681737.  
I have get twice error ablout “unexpected fault address”. The log as follow:

 ![influxdb_exception](https://us1.discourse-cdn.com/flex023/uploads/influxdata/original/2X/a/a6c668bee7e3ebe8162eee184630497a0a57ebfc.png)  
It automatically recovers after 12 minutes, but I lose my some data.  
I don’t know how to solve the problem. Please help to check the reason.  
Happy to provide more information if needed.

Hello @liuyang0716,  
What version of InfluxDB are you running?  
Thank you  
I don’t know if this is useful at all?

Thanks for your reply.  
I used InfluxDB v2.3.0+SNAPSHOT.090f681737 in my single instance and I do not use docker container.  
It runs by “systemctl start influxdb.service” directly
