Getting this error on cloudboost, which restarts the cloudboost server and all sockets connections are lost

What causes this?

Hi @PratikG9 please could you provide the code snippet that is causing this error? That will be real helpful, thanks.

Here is the architecture diagram of our cloudboost development server,

To diagnose the issue we've added logs in /database-connect/realTime.js file at line 131.

18|Locatio | REDIS CLIENT SOCKETDATA :  null
18|Locatio | REDIS CLIENT SOCKETDATA :  {"query":{"tableName":"Streams","query":{"$include":[],"$includeList":[],"_id":"5BDJUx60"},"select":{},"sort":{},"skip":0,"limit":10},"timestamp":"3MnjziOJ","eventType":"updated"}
18|Locatio | REDIS CLIENT SOCKETDATA :  null
18|Locatio | REAL CLIENT SOCKETDATA :  null

from the above logs it is cleared that socketData is null. due to this we're getting exceptions shown below,

@sauban , @nawazdhandala
I think it's due to two different cloudboost instances on the same machine using the same redis server

please comment
