> @DonalEvans Do you have any capacity to assist with this?
I emailed back and forth with Mario a bit trying to figure out a way to
reproduce the issue in a DUnit test, but it's not an area of the code I'm
particularly familiar with so my ability to help was fairly limited. I thought
that if the assumption that the problem was caused by colocation taking too
long was correct, then artificially slowing down colocation by using a listener
to wait a little after each bucket is created could reproduce it.
Since part of the proposed fix seems to be to wait a total of 9000ms for
colocation to complete in `CreateMIssingBucketTask.java`, it seems like forcing
colocation to take close to that long should be a sure-fire way to reproduce
the issue, if the fix is effective. It seems like this wasn't the case though,
so maybe my idea was off the mark.

> Colocated regions missing some buckets after restart

> Key: GEODE-8546
> URL: https://issues.apache.org/jira/browse/GEODE-8546
> Project: Geode
> Issue Type: Bug
> Components: regions
> Affects Versions: 1.11.0, 1.12.0, 1.13.0
> Reporter: Mario Kevo
> Assignee: Mario Kevo
> Priority: Major
> Labels: pull-request-available

> After restart all servers at the same time, some colocation regions missing
> some buckets.
> This issue exist for a long time and become visible from 1.11.0 by
> introducing this changes GEODE-7042 .
> How to reproduce the issue:
> # Start two locators and two servers
> # Create PARTITION_REDUNDANT_PERSISTENT region with redundant-copies=1
> # Create few PARTITION_REDUNDANT regions(I used six regions) colocated with
> persistent region and redundant-copies=1
> # Put some entries.
> # Restart servers(you can simply run "kill -15 <server_pids>" and then from
> two terminals start both of them at the same time)
> # It will take a time to get server startup finished and for the latest
> region bucketCount will be lower than expected on one member
