Sound can be hear after render is finished (SOLVED)

Anybody has this problem too? Sometimes Reaper give out some sound (last buffer or something) after rendering ("render time selection"). Doesn't happen on all projects. Didn't investigate it enough but I don't like this behaviour. Sometimes you get pretty loud bursts and pops (obviously because it doesn't kick in on zero crossings). :(

Yes. I had tentatively surmised it was due to my use of ReaVerb. I may be wrong, I found it easier to trim off the ends of renders than to troubleshoot the issue thoroughly.

Yeah, it's definitely safer do render some silence at the end. I also have ReaVerb in the project where it happens but I'm not sure if it's the culprit.
