turns out it was an issue with 2 collection columns created concurrently on the 
same table; I think it would be have some information in the logs instead of 
the exception alone. Finding the issue can result in hours spent looking at 
system tables.

Couple of notes: while the response to the schema changes returns this error; 
changes take place. Since this problem appeared I always see that FlushWriter 
pool have  0  values in the all time blocked column.
