To Reproduce

root@ddf7471aa162:/workspace# /opt/tritonserver/bin/tritonserver --allow-http true --model-repository=./models/ner-model/  --load-model=*  --allow-http true --http-port 5023 --reuse-http-port true
terminate called after throwing an instance of 'std::invalid_argument'
  what():  stoi
Aborted (core dumped)

When running it with 1:

root@ddf7471aa162:/workspace# /opt/tritonserver/bin/tritonserver --allow-http true --model-repository=./models/ner-model/  --load-model=*  --allow-http true --http-port 5023 --reuse-http-port=1

Your test files cover it with the 1 flag but -h documentation is wrong/not clear as it indicates boolean true/false.

Expected behavior
The command line should execute with --reuse-http-port true.
