Issue with Group migration - Error 503 Backing off

[adjdelta8]

Hi

We are migrating about 25K emails - and we have been able to migrate 2 out of 3 inboxes to google groups, using the migration API in GYB.

However, the third inbox is proving to be very tricky - with about 5K emails.

No matter what we are doing, it is just not working and finally we end up getting these errors:

Temp error 503. Backing off 16 seconds...attempt 5/10

Temp error 503. Backing off 32 seconds...attempt 6/10

Temp error 503. Backing off 60 seconds...attempt 7/10

Temp error 503. Backing off 60 seconds...attempt 8/10

using GYB latest version - but its just not working. We are very far away from the Quota limits - so there's no question of quota exhaustion - checked on the google cloud console - and it is verified.

Please help - any pointers on this would be greatly appreciated!

@adjdelta8 try with --batch-size 4 option.

@urbaned121 This solved the problem so far for me so thank you. Maybe we should open a PR with this as the default.
