I haven't changes the values in hypertable.cfg, just using default ones. These errors occured after some time (usually a long time) of inserting, deleting and updating data, as fast as the computer could produce them and hypertable handle them (in a single-thread loop: produce random data - handle by hypertable - produce random data - handle by hypertable- etc... "handle" means insert, update, delete, get, check if exists or iterate. I wanted to be sure Hypertable will handle constant manipulation)
