[Bug 1321204] Re: upstart (session) consumes almost 3GB of memory after 24 hours of uptime

[James Hunt]

Since the re-exec makes the memory drop down, this sounds like an issue
similar to bug 1235649 - a rogue client is connecting to upstart but
without using a main loop, or not registering the required NIH main loop
callbacks to allow libdbus linked into Upstart to flush the messages it
is attempting to send to the client.

See:
https://bugs.launchpad.net/ubuntu/+source/upstart/+bug/1235649/comments/48

If so, fwics this is not a bug with Upstart, but a limitation of D-Bus
not allowing the D-Bus server to determine if the client is "badly
behaved" and just discard any D-Bus replies the server is expected to
send to the client. The only correct behaviour for D-Bus if it cannot
know if the client is badly behaved is to keep caching more and more
reply messages until the client attempts to receive these reply
messages.

Bug description:
  Running utopic with the ubuntu-desktop-next metapackage installed I
  see that media-hub-server is crashing many times per second (bug
  1321203). Whatever is actually causing that the session upstart daemon
  now consumes about 3GB of memory after running like that for about one
  day.
