Karthikeyan Manivannan commented on DRILL-5448:
-----------------------------------------------
Sorabh and I took an initial stab at this. The failure is because the error
message buffer in Drill::ErrorMessages::getMessage can only handle 10240
characters. The error message, in this case, is about 32k. This seems to be
causing the segfault. No idea why this only occurs if the drillbit is busy.
