"dst cache overflow" messages and crash
...d the route patch from Julian Anastasov. With rtstat I see that the route cache size increases regularly without never decreasing. I have this parameters: fw:/proc/sys/net/ipv4/route# grep . * error_burst:1250 error_cost:250 gc_elasticity:15 gc_interval:60 gc_min_interval:0 gc_min_interval_ms:500 gc_thresh:4096 gc_timeout:300 max_delay:10 max_size:65536 min_adv_mss:256 min_delay:2 min_pmtu:552 mtu_expires:600 redirect_load:5 redirect_number:9 redirect_silence:5120 secret_interval:600 I can increase the maximum size of the cache, but that will do nothing but delay the crash.

The problem is the load is too high on this system. I found a solution to my problem, turning off the route cache, but i dont know how to implement it, I was wondering if anyone found a way to disable the

Nothing suspect appears in the log, so we are at a lost as to what to do next. Any advice would be welcome and/or an explanation of what types of things cause Application 500 Errors in mongrel.

Hardware Configuration Ideas
Hey guys, I am planning to buy some components for a Linux router that will handle the Internet access of 200 computers (includes tc shaping) and some inter sub-network routing (at least 100MBps per eth - and there are 3 eth cards). I was thinking of a: Pentium 4 - 3GHz 256 or 512MB RAM Network Cards. Now - I wonder what is more important: the processor speed or the amount of RAM. And can you
