It doesn't appear to be there with the patches I applied... :-(

I have tried the ingress policing when the new patches, but according to my 
mrtg graphs, it still doesn't seem to work, even in it's simplest form. I 
THINK I saw it work with FTP, though (connection throttled), so I am not 
sure. It could be that it works initially, then stops later. I will 
investigate further...

Yeah, I know. I will upgrade at some point. ;-)

I seem to be having a problem with the newly applied patches, though. After 
6-8 hours, I get a kernel crash. Black screen od death, hex dumps, Aiee, 
killing interrupt handler, trying to kill idle task, etc. This happened 
twice, so it seems unlikely to be a coincidence, as the only patches applied 
were the DS9, rtree, HTB3 and routes. It used to be stable before. I am 
hoping that it is ingress related stuff that kills it, so I have turned that 
off (everything to do with ingress). We'll see if I get another crash now. If 
not, than it would appear that it is ingress policing that kills it after a 
while.

I will report back on this when I know more.

Regards.

Gordan
