The first thing you need to do is scope the errata file to see if your problem is already covered:

Probably the most common error is when ATLAS dies because its timings are varying widely. This can often be fixed with a simple restart, as described:

If you are unable to find anything relevant in the errata file, you can submit a support request to the ATLAS support tracker (not the bug tracker, which is for developer-confirmed bugs only):

When you create the support request, be sure to attach the error report. It should appear as BLDdir/error_<arch>.tgz. If this file doesn't exist, you can create it by typing make error_report in your BLDdir. More details on submitting support requests can be found in the ATLAS FAQ at:
