LHC@home

This morning boinc crashed out unexpectedly. I have managed to get the following lines (see below) out of the *.old files relating to the crash. As i can see it must be related to sixtrack rather than seti or boinc itself. When the crash happened nothing was sent to screen the application just quit. Have others seen this problem and is there anything i should do to resolve this futher?

Lines from logs:
