The 9-b12 promotion performance run on Aurora Performance had 2 of 5 iterations of SPECjbb2013-CMS fail with SIGBUS errors. The hs_err_pid files in both cases are truncated, suggesting that we may have even taken a fault on a fault.

This could be a hardware condition.
[ed. Not a hardware condition, the SIGBUS has occurred on a different machine. See the June 2 comment.]

Please do not access the machine indicated in this bug report. Any access to this production performance machine needs to be coordinated with the Aurora Performance team.
