Dear Managers:
Our AlphaServer 8400 running Digital UNIX 4.0B (with a
variety of patches), with 2GB RAM, 4.3GB swap, has been
crashing repeatedly and producing similar panic strings:
------------------------------------------------------------
trap: invalid memory read access from kernel mode
faulting virtual address: 0x00000000002a38c8
pc of faulting instruction: 0xfffffc0000263ff8
ra contents at time of fault: 0xfffffc00004856f4
sp contents at time of fault: 0xffffffffb50cf288
panic (cpu 3): kernel memory fault
------------------------------------------------------------
We have just installed all patches from the August distribution
(following DEC's advice) plus four kernel modules from the
TotalView Beta Test patches (arch_alpha.mod, procfs.mod,
std_kern.mod, vm.mod).
I have logged a call with DEC but they're still "scaling" the
crash.
Does the kernel memory fault have to do with the patches? We'd
never had this problem before the patches were installed.
Someone has suggested that a lower version of Digital UNIX
might be a solution. Is this true? What problems could we
have if we "down-grade"?
I have seen similar problems in the archives but no useful
solution.
Any suggestion? I'll summarize.
Thanks in advance,
Lucia Gonzalez
