Since you are on 5.6, which has been end of life for a while, the chances of getting this solved are slim.From my memory, I never used the iwodstart perl script to start a WF, but I used iwod start (or was it iwodcmd start) from od-home/bincheck the bin directory and see what choices you have as executables instead of a perl script. If you need to use the perl script, you may need to post that for anyone to remotely have a chance to debug.Also, I am assuming that ther are no hung jobs, esp with that #. If one is running with that -inst value, the next queues up behind is.Try iwodserverstatus (that is a 6.X command, I do not remember what, if any, was the equivalent in 5.6)Andy
