If it won't start again - it could be that TCPIP is having trouble or is not started. Or some other job has the port 1445 you have defined for OD to use. If it was working and then stopped - what might have changed on your system.
The info you've included is from a QPRINT spooled file produced by an OD instance server job, but it is not the joblog. You may have to adjust the message logging level on the QRDARS/QOND400 job description temporarily - 4,00,*SECLVL in order to get a real joblog to produce.
You may want to open a support case so it can be investigated further.
