Joel Knighton commented on CASSANDRA-12164:
-------------------------------------------
I agree that this looks like the same basic problem as [CASSANDRA-10978]. The
problem I found when I researched that issue was that flushes to disk were slow
- I picked 5 seconds because it was dramatically higher than the migration wait
times I had seen. We specified the migration wait period in the dtests because
we thought this was due to running multiple CCM nodes on a relatively small
host, so the problem wasn't likely to surface in real clusters. Hitting this
again could be due to a regression in time to flush the schema keyspace, or it
could be that I just never got lucky in my original investigation.
