Title:
  long-running stunnel leaks memory

Status in stunnel4 package in Ubuntu:
  Fix Released
Status in stunnel4 source package in Xenial:
  Confirmed
Status in stunnel4 package in Debian:
  Fix Released

Bug description:
  We are running a long-running stunnel4 daemon to proxy TLS connections
  to another set of servers. After leaving it running for a few weeks,
  its memory usage had grown to 1.5GB. Restarting it reduced its memory
  usage to expected levels (VSZ and RSS) but while I've been watching it
  today it has grown by more than 10MB.

  The stunnel website indicates that there have been fixes relating to
  memory leaks in versions 5.32 and 5.33, but Ubuntu LTS is still
  running 5.30.
