Hi Everyone, I was migrating the data of wordpress site to my django sqlite3 db.i had relation of M2M in a model (where it crashed). I migrated the whole data into sqlite3 and it works for almost a day.When i reopned the backend of my django and tried to access the data all the time i got 502-Bad Gateway,Whenever i tried to modify records of my data it got crashed everytime. Can anyone explain this behavior to me.I think sqlite3 is a poweful db, why it was crashing all the time?
