Hi,
I cleared up the swap issue being 95% full.
How do I check how priorities are set? Is this a kernel parameter? I have never seen this much activity in the kernel before, what can cause this CPU contention? There is only a small load on the system.
Thanks a million

rump.halt
RUMP.HALT(1) BSD General Commands Manual RUMP.HALT(1)
NAME
rump.halt -- halt a rump kernel
SYNOPSIS
rump.halt [-dhn]
DESCRIPTION
The rump.halt utility exits a rump kernel. The file system cache, if present, is flushed. Since a rump kernel does not control its clients,
they are not directly affected by rump.halt. However, they will be unable to request further services from the halted rump kernel.
The options are as follows:
-d Create a core dump. The core file is saved according to standard userland program coredump rules, and can be later examined with a
debugger.
-h By default the process hosting the rump kernel exits. Using this option shuts down rump kernel activity, but does not cause the
hosting process to exit.
-n Do not flush the file system cache. This option should be used with extreme caution. It can be used if a virtual disk or a virtual
processor is virtually on fire.
SEE ALSO
rump(3)
HISTORY
The rump.halt command appeared in NetBSD 6.0.
CAVEATS
While using -h makes it impossible to issue further system calls, it does not necessarily stop all activity in a rump kernel. It is recom-
mended this option is used only for debugging purposes.
