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.
