mLAb：名称解析暂时失败

Question

I'm not sure how this is happening in mLab or if it's something mLab should encounter. I left my python code processing all night inserting and updating document in mLab. Until I woke up this morning and found the error:

ServerSelectionTimeoutError: ds[....].mlab.com:[...] :[Errno:-3] 
Temporary Failure in Name Resolution

What does this mean and how to fix this?

Answer 1

Can you add the code snippet how you are updating the documents. This usually happens when Python code cannot resolve the domain name or DNS lookup issues.

• Two things I suggest would be to check how many of your records got inserted/updated in mongo lab.

• Code snippet which does this post request(Since mongo lab API actually does a POST of document that you actually insert/update. Check if it has a an option allow_redirects=False and set it.)
