Seems to be some async pipeline issue.

ERROR: EOFTk went missing in AsyncTokenTransformManager

This also seems to result in these errors in ParserService

Can't set headers after they are sent.

Stack trace: Error: Can't set headers after they are sent.

Meanwhile, will look at making migrateStartMetas more robust if it makes sense in this case.

Change 71169 had a related patch set uploaded by Subramanya Sastry:
(Bug 50408) Make migrateStartMetas more robust

https://gerrit.wikimedia.org/r/71169

Because of the 'Cant set headers after they are sent' issue, this fix wont prevent the workers from crashing.
