---------------------------------------------
Hey,
I do not see enough information to debug and to investigate the problem. The
exception stack is unclear for me from majorCompaction() what is the path to
getCell() from CCM (which is the only place to throw this exception)? Please
let me know in case the problem can be reproduced.
Generally speaking, I saw this exception once when there were no more chunks in
pool, but the problem was fixed long ago. What version of the code is used
here?
