[LDM #CUW-137953]: ldmadmin bug using break instead of last

Brenda,

You're absolutely right! Kudos!

I guess I have C on the brain.

Your fix will be in the next release.

> ldmadmin is a perl script.  It uses a command "break" which does not exist
> in perl.  The correct command is "last".  The "break" is on line 672 of
> ldmadmin in version 6.10.1
> 
> Here is the ldmadmin snippet:
> # Check to make sure the LDM is running
> my($loopcount) = 1;
> while(!isRunning($pid_file, $ip_addr)) {
> if($loopcount > 15) {
> errmsg("start(): ".
> "Server not started.");
> $status = 1;        # failure
> break;     # This break needs to be last
> }
> sleep($loopcount);
> $loopcount++;
> }
> 
> The symptoms are that "ldmadmin start" is stuck in a loop putting out
> "start(): Server not started." messages with sleeps between increasing at
> one second intervals.
> 
> The "break" was supposed to break out of the loop after 15 iterations and
> the "Server not started" message, but it does not do that and the loop
> continues forever.
> 
> We found this bug in at least version 6.10 and 6.11 in use.  We checked
> source for 6.12.14 and it it there as well.
> 
> This symptoms have been reported in the unidata forums, but I did not see a
> resolution.

> 
> The fix will not change why it would not start, but should prevent the
> infinite loop that occurs now.
> 
> This issue is also sometimes associated with the following error message
> (perhaps why the server did not start?):
> 
> ulog: Couldn't connect(2) to UNIX socket "/dev/log": No such file or
> directory
