I still don't understand how the monit restarts are not causing problems now.
2015-10-26 29950, 2015
zas
because they don't restart at the same time
2015-10-26 29913, 2015

to my understanding, this is the main cause: one server down, load balancer puts all load on the other, the other drop, no server, first one starts take all load during startup, can't handle it, second server starts, load balancer sends all load to it, can't handle it, etc....

nginx recent versions has a slowstart feature, that could help in this imho (not sure which version has it though)

that would be perfect!!

btw, it can still happen, if we are unlucky

heavens no.

it is our own system on top of lucene, hosted in tomcat.
but given that it's actually working, I suspect that your search load doesn't really need caches warming

well, the core issue is that we need to restart those damn search servers far too often (2 days ago it was every 10-15 minutes), mostly because they eat memory as hell, and because of indexes pushs (about every hour), i reduced the number of restarts, which reduced the "chance" for them to go mad, but it is more a workaround that a fix.

nginx plus is the non-free version ? according to docs, the slow start is an nginx plus feature

LordSputnik: MSID != MBID, and I guess an MSID→MBID matching can change over time.

well, they may if it’s wrong
2015-10-26 29952, 2015

but, e.g. I don’t think we should change if 2 other mbids are merged

alastairp: I was thinking that initial mapping might prove wrong.
2015-10-26 29941, 2015
alastairp
right
2015-10-26 29959, 2015

my hope is that we get it right the first time - that is, don’t make a mapping unless you’re sure
