WITNESS messages in Mar 21 Kernel

[Hiten Pandya]

Hi All,

I have been getting a witness message every now and then, which someone
might be interested to have a look at:

        witness_get: witness exhausted

I am currently trying to trace this out, but maybe someone already knows
why it is being generated.  I didn't get this message before the Thu Mar
21 kernel.  I am attaching my uname output below, with my kernel config
file, if someone is interested.

FreeBSD hpdi.ath.cx 5.0-CURRENT FreeBSD 5.0-CURRENT #2: Thu Mar 21 20:05:18 GMT 2002   
  [EMAIL PROTECTED]:/c1/obj/data/dev/src/sys/CURRENT5  i386

Thanks,
Regards,
