Re: BUG #14948: cost overflow

Hello,

in the meantime we managed to not trigger the OOM kill anymore and now
also don't have this problem with the negative costs anymore. We still
have one staging environment where this error is present, but we would
like to reclaim it. Is there some guidelines I can follow to debug
this?
