This is on branch release-6.0. (tested both on Ubuntu 18.04 and mac)
I tried to run the KVStoreMemTest (except I changed the nodeCount to be 2000) using command
./bin/fdbserver -r simulation -f tests/KVStoreMemTest.txt -s 6
Insertion part works fine, however, when it came to scan part, i got the
Internal Error @ fdbserver/workloads/KVStoreTest.actor.cpp 168
My first guess would be the assertion failure, wondering if anyone else has the same problem.
