Hi folks,

we have a DEC PW600au running DU4.0e which has been crashing several
times in the past few days.
The culprit seems to be a 'decsound' process:

[...]
14712   decsound
_kernel_process_status_end:
_current_pid:  14712
_current_tid:  0xfffffc0009b52700
_proc_thread_list_begin:
thread 0xfffffc0009b52700 stopped at  [boot:1931 ,0xfffffc00003e05dc]   
Source not available
_proc_thread_list_end:

Could anyone give a hint whether this is really a CPU problem
or perhaps the sound card or ...?
I would also appreciate any hints what I could do for further
analysis (what does 'machine check code 98' or 'too many processor
corrected errors on cpu0' indicate?).

I attach a few excerpts from /var/adm/messages and 
/var/adm/crash/crash-data.

Thanks in advance & a Happy New Year,
Volker
