The main web server which also has about six virtuals on it died this morning, apached OOPS'd out. There appears to have been a packet flood just before this and because it also affected other servers that have ICMP and UDP blocked, I suspect it was a SYN flood. The other servers (not running Apache) held up OK. This apached was also compiled during a time when we had a version of egcs that was buggy in place. I've recompiled Apache, set the size of the backlog queue larger so that it will be able to handle a larger flood without dying, and increased the frequency of scoreboard processing so that it can ramp-up the number of processes faster during either a flood or just a heavy traffic burst.
