We have a few very busy web servers here, and we're running in to a bug in FreeBSD 4.2 (which is related to a bug in previous versions of FreeBSD - the one that's fixed by lowering net.inet.ip.rtexpire to 10 from 3600) where the dynamic route table grows but never flushes completely. Here it is just as it hit the buffer space limit, according to vmstat -m: Memory statistics by type Type Kern Type InUse MemUse HighUse Limit Requests Limit Limit Size(s) routetbl608495 85570K 85570K 85570K 51402924 0 0 16,32,64,128,256 The sister server (round robin) is pretty high as well: routetbl280443 39437K 39443K 85570K 37217727 0 0 16,32,64,128,256 Also, if this happens again, what additional information could I grab so I or others could (hopefully) successfully find the bug?
