I realize you've solved your problem, but I thought I'd share a similar slow-startup problem that we ran across that I would have suggested had I looked at the thread earlier. Adding here so that it makes it into the archives.
One of our apps allowed users to upload files. These files were stored in a directory that was deep within the WEB-INF directory of the webapp. As the number of files grew very large (100's of thousands), we found that the webapp was taking longer and longer to startup. Later we found that at startup time, resin was doing a search through all WEB-INF subdirectories for any taglib files. I don't know if this was a misconfiguration on our part or just normal behavior. Our simple solution was to put the directory of uploaded files elsewhere and keep the number of files inside WEB-INF to a reasonable number. This may not apply to all versions of resin (we made that change in the resin 2.x days) but it's just another potential slow startup scenario for future reference.
