Sitution:
1 CPU system running Resonant and apache
Solaris 9 (with opportunity to go to 10)
System goes nuts with 100% cpu, very high kernel usage (99% vs. user at 1%)
and very high load averages (> 30) (uptime, top)
Little or no I/O load (top, iostat)
Lots of memory, lots of swap free (top, vmstat)
No significant mutex locks (mpstat)
The question: Is there a tool for Solaris 9 that will tell me what process is
using so much kernel code. Or if I have the opportunity to go to Solaris 10 a
dtrace script that will show me the same thing.
