Memory error causing reboot
Hi there

I have a box that at 4pm started recieving soft errors on a DIMM, normally this is ok and we have time to swap it out. But I got the following error which caused the box to reboot

NOTE: there were abount 6 or 7 normal "soft error encountered" messages before this one

Code:
Nov  7 16:02:37 my.box SUNW,UltraSPARC-IIIi: [ID 667005 kern.info] [AFT3] errID 0x00212a5e.7a11dcbb Above Error is in User Mode

rrID 0x00212a5e.7a6b8682

My question is this really, is it possible that when an process tries to access the specific bad area of memory on the DIMM it can cause the box to reboot .......because in the above example, its only when the process (apas_OaLgw) gets involvedf that anything happens

any help would be greatly appreciated

Yes it is possible..

From sunsolve:
"On EDP, LDP, CP, UE, BERR, and TO events the system will panic if the address is in kernel space or if the error occurs while the CPU is at a trap level greater than zero. Otherwise, if the affected address is in use by a process, the process will be killed immediately (sent SIGKILL) and the system will be rebooted (as if a privileged user had entered "init 6")."
