[j-nsp] DRAM for M7 / crash of M7

[Matthias Gelbhardt]

Hi!

The reason I wrote is, that we have a M7 with 256 MB DRAM. Yesterday I  
configured three iBGP sessions and one eBGP session. In total I got  
around 600000 routes from which 260000 were active. The receiving and  
advertising process was finished also the best path determination.  
After a few minutes I checked back on the router which is located in a  
datacenter, but I got no reaction from it, also no ping or trace  
reaction.

After a reboot in the morning, I was able to analyse the logs:
Aug 25 18:05:56  muenster rpd[4195]: RPD_OS_MEMHIGH: Using 215998 KB  
of memory, 144 percent of available

I think this clearly states, that the 256 MB of memory are not enough.  
So we are now trying to upgrade it. I am surprised, that 600000 routes  
are obviously too much for this router. Will 786 MB do the trick also  
for a higher count of routes?

Regards,

Matthias
