I must admit, after deploying 1.6.2 to production, I am still seeing more memory usage than expected. I was going to take some time to gather some more stats - but seeing this made me jump early :)
Memory usage is still better than it was originally, but I see 2G in some cases, which seems pretty excessive for 2500 routes. The other strange this is, I see a lot of variance across hosts with the same route count, config, and similar process run times. Some node processes are using 12Mg - 16Mg, while some are using up to 2228Mg after just one day. The bird.conf has changed a little, so I'll attach it again here. Madhu - perhaps you should provide your bird.conf as well ? Also - some basic info: # birdc BIRD 1.6.2 ready. bird> bird> show route count 2484 of 2484 routes for 1245 networks bird> show mem BIRD memory usage Routing tables: 2235 MB Route attributes: 87 kB ROA tables: 192 B Protocols: 41 kB Total: 2235 MB If you need any further info - please let me know.
