Memory Fault

Vito Sarducci — Fri, 19 Apr 2002 12:07:23 GMT

I had this error last night in my cron activities and was wondering if anyone knows what this might be?

/usr/lib/sa/sa2[10]: 24986 Memory fault (coredump)

Please advise?

Hi,

What is the line in your crontab?
Is it something like:

#reduce the sar data
5 18 * * * /usr/lbin/sa/sa2 -s 8:00 -e 18:01 -i 1200 -A

grt, E.

What happens if you run this line from the prompt?

/usr/lib/sa/sa2 -s 06:00 -e 18:01 -i 1200 -A

Vito,

Check if patch PHCO_25174 is installed on your system. If not, install it, it's a known problem for sar to coredump when extracting
data from a previously recorded file that contains RESTART
records.

HTH, Emiel

Vito,

Try to change start time to 06:01 as follows:

05 18 * * 01-05 /usr/lib/sa/sa2 -s 06:01 -e 18:01 -i 1200 -A

This is a work around. I ran into this problem before.

One more patch for you to check, make sure you have the latest libc cumulative patch ie PHCO_25707 (for 11.00), this patch updates libc library used by sar.
