Return code of 127 is out of bounds - only on high cpu load though

[Daniel Wittenberg]

I ran a full strace of nagios daemon and children and it looks like it
was the enable_environment_macros that was causing:

[pid 20478] execve("/bin/sh", ["sh", "-c",  . . . . . ] = -1 E2BIG
(Argument list too long) <0.000337>
[pid 20478] exit_group(127)             = ?

I turned them off and that fixes things, but potentially breaks some
other things in our setup, but for right now it's working.  Still odd
that as I change the number hosts the env changes enough to push over
the edge.  I ran same tests with only 300 hosts and it worked fine, just
looks like at about 500 or so something changes in env.

Always something fun in nagiosland :)

Not those two, no. They should be fairly well behaved, unless you're
using check_tcp with ssl and your ssl library is acting up. I can't
see how that could be happening though. What does the debug log tell
you?

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
