If it's easy, would you mind trying with the patch on PHOENIX-1675 to see if it fixes the issue?

+1 on putting together a unit test for this.

> If total number of parallel iterators + mutation count exceeds Phoenix thread pool size then immutable index remains at 0 rows with no activity on client and server.
> Ex. Only with guide post count of 64 or lower does immutable index gets build with default 128 thread pool. By changing guide post width to get with >64 guideposts, index fails to build. Also if thread pool size is lowered from 128 then index fails to build for 64 guide posts.
> Let me know if you need a utest as I think it would be easy to repro in it too.
