Do other jobs start in this cron table? Might be a typo or wrong
permission in it?

Doesn't tcpser listen on a port? If it was still running (under a
different name, why ever that may have happened) the port already in use.

May be next time it seems to have stopped also test if the port it runs
on is still used. Something like

lsof -i :1234 (< replace by actual port)
