Strange (and varying!) number of CPUs in backhand status

Hello,

When I request backhand status (via the backhand-handler handler), I see a
strange behavior where the "# CPUs" statistic changes over time, and is
also entirely wrong (I see values in the range of 8-11 when there are in
fact only 2 CPUs on this test machine). Also, "# ready servers/# total
servers" always shows 0/0, even though there are clearly Apache children
running and active.

Is this a known behavior?

Information about my setup:

% uname -srm
SunOS 5.7 i86pc
% httpd -v | grep version
Server version: Apache/1.3.19 (Unix)

I am using mod_backhand 1.2.2, with platform.c updated to revision 1.23 so
it would compile on Solaris. mod_backhand was compiled as a shared module
using the apxs build process.

Humbly,

Andrew

The 0/0 is documented in the FAQ.

What does psrinfo -v return?

It seems to work okay on my SunOS 5.9 i86pc box.

This is a dual PIII box.

% psrinfo -v

Processor has been on-line since 08/02/03 16:28:37.
The i386 processor operates at 708 MHz,
and has an i387 compatible floating point processor.
