we have non reproducable errors where kallithea return 417 or 403. Not often, but from time to time.
Background: We use Kallithea very heavy (CI clones and pulls often)
We try to debug this.
Maybe this is a reason for the sporadic errors:
Exception AttributeError: AttributeError("'_DummyThread' object has no attribute '_Thread__block'",) in <module 'threading' from '/usr/lib/python2.7/threading.pyc'> ignored
No other information is in the apache error log (no stacktrace) Do you have an adivce?
How can we find the root of the sporadic errors?
