db-server crash under heavy load with redis-benchmark

[ogoudron]

I use the last version of redis-benchmark.

This is the command used to crash db-server :
./redis-benchmark -t set,get -n 1000000 -d 1024 -r 1000000 -l

After 2 or 3 loop, db-server crash.

Bests regards, Olivier Goudron

Thanks again for your reactivity, i will test it today.

If you don't want to data recovery(if server crash) , change to IS_LOG_RECOVERY (0) in 'db-server.c', this is fast for performance.
