T44362 reports a huge number of skipped item IDs when new Wikidata items are created.
We should understand what leads to the issue that prevent creation of new Items, and in turn to "skipping" the ID.
In particular, it would be important to find out if any of the recent code changes has increased the "conflict" rate - @Lucas_Werkmeister_WMDE suggests that recent change of the ratelimit for bots might be one of the factors relevant here (T258354).
WMDE has recently look into the related problem in T232620.
There is a number of hypotheses of issues that could be leading to creation problems, reported as:
T264448: Entity ID should not be assigned for label/description conflict
T264449: Entity ID should not be assigned for invalid entity data
T264450: Entity ID should not be assigned if rate limit is hit
T264451: Entity ID should not be assigned if disallowed by AbuseFilter
Investigation does not have to limit to investigation those four possible causes.
Investigation will be timeboxed to 20 hrs.
