It happened after I upgraded it (calling LBC -u). Everything went fine, I even did the LBC -x and no problem. But when I called it for LBC -c 2 -id xxx -s xxx, it said ... Answer: too fast.

I doubt LBC -x went through without a problem. Because the benchmark claims your computer did 16M keys in 0.002s, so either your computer is from the future or something went wrong.

The result of the test:
time ./gen-hrdcore-sse42-linux64 -I 0000000000000000000000000000000000000000000000000000000000000001 -c 10000 -L 1
but the first key must be in the range:
1 - fffffffffffffffffffffffffffffffebaaedce6af48a03bbfd25e8ccf364141
Please retry with another key
Something went wrong. The generator failed internally somewhere. For diagnosis send me
