swi4: clock taking 40% cpu?!?

[Doug Barton]

Howdy,

Web server under heavy'ish load (7 on a 2 cpu system) running
8.2-RELEASE-p4 i386 I'm seeing this:

PID USERNAME PRI NICE   SIZE    RES STATE   C   TIME   WCPU COMMAND
12  root     -32    -     0K   112K WAIT    0 129:01 39.99% {swi4: clock}

Any ideas why the clock should be taking so much cpu? HZ=100 if that
makes a difference ...


Doug
