Description tuqiang2009 2011-05-17 11:01:08 UTC

with dbus 1.4.6, after about 10M calls, I got the error "invalid request, socket fd 7 not open".But never get a disconnected signal. There are 2 issue here:
1. why the fd become invalid
2. If the fd become invalid, need a disconnected signal so app can try to reconnect.
It reproducible without verbose log, but take too long to reproduce it with verbose log.
Any suggestion?
Thanks

looks the reason the connection is disconnected is:
before I use DBusConnection *, I use dbus_connection_ref and later dbus_connection_unref, somehow dbus_connection_unref will call _dbus_connection_last_unref even I'm sure I call dbus_connection_ref and dbus_connection_unref in pair.

Can you provide source code that reproduces this issue?

You might find it useful to apply the patches from Bug #37286 and run under valgrind with DBUS_CONNECTION_TRACE=1 in the environment. (This will take a long time, but will indicate where your connections are reffed/unreffed.)

More information requested 3 years ago and not supplied; there isn't enough here to diagnose or fix a bug, so closing as WORKSFORME.

If you have this symptom, please open a new bug (or reopen, if you are the original reporter) with more information.
