Error



BAD TRAP: type=10 rp=2a100b357d0 addr=600dc72ea80 mmu_fsr=0

 


Cause



This particular panic of the system, running Solaris 10 with Kernel patch 137137-09 on SPARC occurred due to "illegal instruction", which a hardware error. This panic was not caused by VxDMP.

If such a panic of your Solaris system occurs, please open a case with Oracle/SunW for further analysis and confirmation, as well.

 


Solution



Per analysis from Oracle/SunW HW Engineering, it appears that the issue is dute to  SUNW Bug ID: 6868072  <<<

Synopsis: illegal instruction or I-MMU miss panic happens instead of D-MMU miss

The symptom of this bug on a OPL box is to show as a illegal instruction fault making it looks like a possible CPU issue.

CR6868072 is fixed in 143911-01 (obsolete) and now rolled into KP142909-17 and above (current is KP144488-04).

Please contact Oracle/SunW for the above patch.

In case of a VCS cluster, please install this Oracle/SunW patch on all nodes, running Solaris 10, in a VCS cluster taking a proper action.
