Re: Memory diagnostics
Use the STM diag suite:
cstm => character based
xstm => X-window GUI
But if you're truly getting mem errors there will be entries in the syslog.log file. And if it's serious errors they'll be multi-byte errors as single errors are correctable & not uncommon - unless constant.

Jeff

Re: Memory diagnostics
The best utility will be STM. Try these commands to check memory:
1) stm - check memory modules (hardware)
2) gpm - GlancePlus memory usage/leak/paging
3) sar - system activity report
4) top
5) swapinfo
6) vmstat - virtual memory
See the man pages for more information
HTH,
Shiju

Re: Memory diagnostics
# cstm
cstm> map
cstm> sel dev
cstm> exercise
cstm> map
===> look for status of the exerciser since it'll take some time for it to complete.
After completion ..
cstm> exerinfo
cstm> exerfaillog
cstm> exeractlog
to get details of report from running the "exerciser"

Re: Memory diagnostics
I normally run the exercise with the maximum option selected. You can also do a q4 analysis of the crash files in /var/adm/crash to determine the reason for the crash.
Hope this helps.
