Sounds very much like inetd service respawn rate limitation. The default rate limit is usually something like 40 accesses/minute. See your inetd documentation for exact value of the default limit and how it may be tuned. The purpose of this limit is to limit the DOS attack to only the service attacked and not bring down the whole machine by resource exhaustion (memory, processes, CPU). -- Henrik Nordstrom
