i tested run while loop trigger from frontend-taskqeue

  1. to backend. after 15mins, i get Process terminated because the backend took too long to shutdown.

  2. to backend and spawn a thread, _ah/background Process terminated because the backend took too long to shutdown.

Can backend run taskqeue more than 15min?

Yes it can run for hours as their documentations says, but this famous error "backend took too long to shutdown" used to appear for tasks takes up to 2 hours sometimes and some other times it may reach 4 hours before stopping the backend.

Can you check the Admin console and see if you have exceeded your quota for backend tasks. You can control the number of instances and the class using backends.xml.
