[solved]Backend errors(s) TECHNICAL_ERRROR:[object:Object]

[saif421]

My frontend is working fine but when I open my backend first of all it takes a lot of time to open.

 

After opening It pop ups an error " TECHNICAL_ERRROR:[object:Object] "

 

If I open any link like Catalog/Customer/Modules I get following error:

" Bad SQL query
MySQL server has gone away"

Open up the browser console (f12 on chrome), tab to network and check for the entry that fires the alert. See its response (filter by "xhr" if you have trouble locating it) and take a screenshot.
Also, turn on dev mode as my signature describes

Hmmm just guessing here. You're running out of resources, apparently. You probably need more memory. Or, the tab is corrupted, and you can try repairing it with phpmyadmin
