I've seen posts about this issue on current@, but without any solution.
Maybe my case will help to shed some light on this one.
2 Cpu 5.4 STABLE (from today 09.07.05) running without any problems.
The kernel is almost a GENERIC, except:
Enabled:
SMP
SHCED_ULE
IPSEC
IPSEC_ESP
INVARIANTS
INVARIANT_SUPPORT
some devices disabled, some added (scbus,da,snp,pf,pflog)
Today I wanted to move a service to this machine which uses a lot
(about 70) network aliases from a few subnets.
First, I have experienced spontaneous reboots, mostly during the rc phase,
but sometimes a little bit later, i.e. after the system is up with simple
services (httpd, named, sshd) and I log in and do something network related.
(but not sure if this is not something else.).
However, the machine was not under even medium load.
When i reduce the number of aliases to about 30, instead of hard reboot
I get a panic:
sched_add: kse 0xc1c40f60 (named) already in run queue
This might be some trail; the panic usually occurs when the named is used - during
the rc phase of setting up network services or after, when doing something network
oriented. Unfortunately, I didn't make any tests without named enabled
(I should have thought of that :(( )
The named is bound to all the ip's of the interface, sshd to only on of them, httpd to
a wildcard address (so said sockstat)
setting kern.smp.disabled in bootloader fixes both issues (but wastes one cpu ;( )
I have a core dump and a kernel with debugging symbols, so please e-mail me if it
needs to me shared. The problem with it is that it is big (500mb) so If You would rather
download a movie from e-mule instead, please request for any info i can dig with kgdb
You need. I'd really like this to be fixed, so I'm eager to help!
Here's a backtrace:
