host is locked by another test UFT ALM error

When I was running the UFT tests from ALM, I saw this error "host is locked by another test".

I tried to stop the test. Test was stopped but even When I tried to rerun it, error did not go away.

Solution

To fix this error, I went to task manager and then killed "uftremoteagent.exe" process

Other solution is to log out of ALM and then login back.
