I know I use this feature in Perl to do timeouts with SIGALRM. Basically, you wrap a block of code around calls to alarm(). If the code does not return in the alotted amount of time, a SIGALRM is thrown. If the code doesn't catch it, the program usually dies with the message "Alarm clock". So, to make a long story short, this is probably a script timing out. If that is the case, and you don't want to see these messages anymore, create a handler for SIGALRM.
