Still a memory leak

[alierak]

I previously noted an apparent memory leak in several workers under Perl 5.14.2. We upgraded the Encode module because it had a known memory leak bug and seemed relevant, and that did actually slow down the memory leak somewhat. However, I now need help brainstorming what could still be causing this. The affected workers seem to be synsuck, send-email, and resolve-extacct, so I've set cron jobs to restart those every so often.

Honestly, what can resolve-extacct be doing that causes it to grow to 9GB in size over the course of a week? We will probably have to resort to profiling memory usage to figure this one out.

Semirandom guess: DW::External::Userinfo uses a process cache somewhere that's never cleared.

OK, that is a wicked odd set of processes to be memoryhogging. And I think the only thing they have in common is that they touch the user db. Any objections to me trying to unspool this from the outside?
