I am using PuTTY command line to connect to a server and tail a log file. On local machine I've created a file "tail-exec" which contains following text:

tail -f /var/log/test.log

I am starting putty through command line as:

putty -ssh -t -pw -m tail-exec user@server

This opens up the terminal window with log tail. But the problem is that this terminal hangs after there are few hundred lines added to the log.

If I open putty manually, and then run the tail command from the bash prompt, then it is not hanging for thousands of lines also.

I've tried using following text in tail-exec file, but same issue is happening:

bash -i tail -f /var/log/test.log

Any idea what could be the issue?
