Work units not finishing

I have had a considerable number of resent units fail. Running on Linux. Seem to have no other apps with issues, but is centainly possible I have not run into the same kind of issues yet with other apps. What I am saying is that it is possible that there is something wrong with the Linux installation but so far I do not know what. Anyway any help nailing this down would be great. The units run for a while and appear to finish, but they really hang. Serveral have dumpped info, here is the info from the last one. They are not always the same also.
