Greater than 1371 Bytes Output Hangs Session

From home, I use putty to ssh into a server at work running Red Hat Linux release 7.2. Commands that display a small amount of output work fine but if I send more than a certain amount to the screen, the session hangs. The system does not respond to ctrl-c or ctrl-d but I am able to duplicate the session and re-login. ifdown eth0 followed by ifup eth0 from the new session does not fix the problem, but I am able to kill the hung session and continue working until I send too much output to the screen. When I use putty to log into this server from a computer on the "inside" network, this problem does not occur.

By experimenting with various file sizes, I determined that I can repeatedly and successfully cat a file containing 1371 characters. When I try to cat a file with 1372 characters, nothing is displayed and the session does not respond to standard input. This should be a pretty good clue.

If someone recognizes this issue, please let me know what it is. Otherwise, I would appreciate some suggestions as to how to troubleshoot this.
