The "U" indicates that it is a "user" error code, we have to look to the user that posted the error to figure it out. Can you provide more information, like what were you executing when you recieved the error?

Please post the jcl from the abended job and whatever error messages were created. There are multiple places where error info might be shown, so look thru all of the sysout data for the job - especally the info from jes. There will most likely be some info in the sysout(s) from the abended step as well.
