I'm trying Roller 0.9.8 again after backing out last week. The main reason I'm trying again is my site was crashing over the weekend, after months of being up without issues. Damn. The main issue I'm having with 0.9.8 is that MySQL connections get up to 20 (the max allowed by my ISP) and then the whole connection thing shuts down (or something like that), and according to my logs - the database is down (when really, it's not).
My attempted solutions to fix this problem are twofold. First, I grabbed the oscache.properties from tools/oscache-2.0b2, rather than using my old one. When building Roller from CVS, there is no oscache.properties in build/roller/WEB-INF/classes, so that's why I copied my old one. Second, I cleaned out WEB-INF/lib and refreshed it with WEB-INF/lib from 0.9.8. I always just copy over the last install when upgrading, so it's possible there were some old jars lying around in here.
If this doesn't work (you'll know if this site is down), I'll have to get a fully clean install from the SourceForge downloads, rather than my own built copy.
