DDSPE errors on Sun V210/V240 systems
Hello,
I am having quite some DDSPE errors (up to 50 per day) on several Sun
V210/240 systems running Solaris 9:
SUNW,UltraSPARC-IIIi: [ID 329692 kern.info] NOTICE: [AFT0] DDSPE Event on CPU0 in User mode at TL=0, errID 0x0006f281.edfa67d2

SUNW,UltraSPARC-IIIi: [ID 304053 kern.info] [AFT2] Parity errors found = 2
Replacing the main board/memory/CPU has not solved this issue.
Instead, the problem seems to be related to Check Point VPN-1 NGX.
Has anyone any comments on this error? I know it concerns correctable
parity errors in the CPU's data cache (DCache).
Would it be possible for software to introduce parity errors on the CPU's
DCache?
Regards,
