Sun's license manager client software does not seem to properly
detect some kinds of license manager server failures.
For instance, right now ziggy is wedged (it seems to have a full
listen queue and does not respond to TCP SYNs on port 1701, ostensibly
the license manager port).
Running "attach sunsoft; /mit/sunsoft/sun4bin/dbx" just hangs for
minutes.
truss-ing it shows it hanging on:
getmsg(4, 0xEFFFEAAC, 0xEFFFE9F8, 0xEFFFEA04) (sleeping...)
And tcpdump indicates:

Sun should be flamed for not having their clients detect this broken
condition in a timely fashion. After a minute or 3 you finally get a
prompt, but the timeout takes too long. It should also indicate the
nature of this failure so users can report problems with the license
server.
