It is hard to know. Is MathLM running on the same computer that you are 
running MathKernel? If so, check to see that you haven't inadvertently 
set yourself on a timed lease.
If MathLM is on a remote computer, you should try and log on to the 
computer that serves the license and check the log file (assuming you 
write one) to see what happened. Then restart it, assuming you are the 
system administrator and assuming that MathLM had crashed. When this 
happens, is the server still running? Can you log on to it?
There is also the issue of connection quality. So, if the connection is of
poor quality, you will lose signal from time to time. 
What version of MathLM is it?
What OS is it running on?
Are you the only user?
