MRP Job numbers error

Length is 6 
next is 118787
 

We just recently started running the mrp process and it worked fine for a while. Now we are seeing the following error in the log file:


The system runs out of available job numbers


Obviously, no new jobs are created. 


Has anybody experienced this? What causes this?


Any help would be appreciated.


In the company configuration there is a setting for job number length and next job number.  What is yours set at?  What is your latest job number?
