SUMMARY: malloc failed

Danny Johnson was correct in that it was not a memory problem. Most
replies pointed to ulimit/limit and excessive logins. Neither was the
case. Several people asked how much memory was in the system; 4GB of RAM
and 1GB of swap. Not likely sar is going to eat up that much memory,
especially since swap -s showed 3GB still available.

But the Pint of Choice goes to John Dodge:

"This is a common problem, check your crontab entries and make sure you are
not running the /usr/lib/sa/sa1 script twice at the same time. typically
int the /var/spool/cron/crontabs/sys file there are two lines executing
the /usr/lib/sa/sa1 script so you need to make sure these are never
executing at the same time."

I looked and, sure enough, there they both were, running like little
hamsters. I commented one out, removed all the previous sa files (they
were no good anyway), and, so far, have good data that I can look at
without a malloc error.

I am trying to run sar on one of my servers but I keep getting the
following error:

sar: malloc failed
Not enough space

Originally I was trying it with sarcheck but that wasn't working so then I
tried it with sar. I get the same error in either case.

What space is it trying to use? I have checked my filesystems and the
lowest available space is / at 33MB avail. /tmp shows a little over 3GB
avail and swap -l shows the same. So, either way I should have enough
space, or at least enough in conventional terms.
