Benedict commented on CASSANDRA-10579:
--------------------------------------
I've updated the branch to also check for this error on construction of the
cell, so that the problem should be elicited by the commit log segment
containing the problematic data. If the problem is deterministically induced by
data in a segment, this will reliably produce the error while processing that
segment (so you shouldn't have to do any maths - just the one it most recently
logged).
Out of interest: have you disabled assertions on your node?

> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Environment: 2.1.10 on linux
> Reporter: Jeff Griffith
> Assignee: Benedict
> Fix For: 2.1.x

> Sometimes we have problems at startup where memtable flushes with an index
> out of bounds exception as seen below. Cassandra is then dead in the water
> until we track down the corresponding commit log via the segment ID and
> remove it:
