Slave lag causing "API response Error for PreprocessorRequest"
Closed, DeclinedPublic

Description filter by error

Occasionally (10 times in the last hour), Parsoid sees these errors, which occur while trying to render (wt2html) a page seconds after an edit. This seems like mysql replication lag to the slaves the mw api servers read from.

@GWicke suggest retrying the request after a short delay, with maybe using [[ | maxlag ]] as an interval hint.
