Kernel panic: "panic: leaf should be empty"

[Kenny Gryp <gryp@dakin.be>]

Hi,

I'm having a problem with one of my servers lately. The machine crashes 
at random times.
I've had the same panic several times.  First my syslog will output 
"vnode: table is full" and then the machine will crash. The output 
below is from a crash at 1u30, just when the daily script was started. 
So I think the problem is with the number of open files.

Would the problem be solved when changing kern.maxvnodes to a higher 
number?
I already changed my apache configuration so it would take at least 
half of the files it was before. (i checked it with fstat)

I'm running OpenBSD 3.4 (x86), i can't give you a `dmesg` yet because 
it just crashed again and
its colocated. It crashed just after i updated to OpenBSD 3.5, which 
was running fine, but when i left to the cinema and came back it was 
down.
I'm not sure yet if the problem is still the same, but everything seems 
the same. I can give more information(dmesg, current kern.maxvnodes, 
same panic or not ...) tomorrow when i go to the data center.

I hope someone knows how to fix my problem. :(
