>Description:
Recently (I think since going to 1.2 alpha), I've been
getting really weird CPU resource utilisation figures from
my shell's (tcsh) "time" command. I've also noticed the
same thing with /usr/bin/time, so it doesn't seem to be
some misinterpretation on tcsh's behalf.
I've getting output like the following:
382.351u 3962.609s 0:50.00 8689.9% 0+0k 0+0io 0pf+0w
2306.537u 14909.980s 0:46.90 36708.9% 0+0k 0+2io 0pf+0w
2640.456u 27579.969s 51:09.11 -414.-7% 0+0k 49+851io 284pf+0w
The problem doesn't occur all of the time - at a guess I'd
say about 50% of the time...
I've only noticed this problem on the pmax port - at least
I haven't seen it on i386, which is the only port I have
access to.
>How-To-Repeat:
Type "time <command>" for commands that use a reasonable
amount of cpu time ("make" and "make clean" down in /usr/src
somewhere are good choices.
>Fix:
Unknown.
