Snowball fight cleared my head. Came back and did a ton of reading and work. I thought everything was working, spreading the load between the 3 servers, but some weird crap's been happening now. The URL parameters are sometimes not visible to the actual machine you hit.... Have to debug. bleh. might sleep and do it tomorrow.
Did upgrade MySQL though.... this version is supposed to bring the query that makes mysql segfault and show a backtrace.... so now we can turn the directory back on, watch how exactly MySQL dies, and get them to fix it.
... always working around other people's bugs. *sigh*
