Which release you're using?
My first quess would be that the device runs out of memory (because
something (Canola?) is using a lot of it, maybe because it leaks) and
allocations are denied to applications (by kernel) and if that happens
inside anything using Glib (such as Gtk), the Glib aborts the process.
How much free memory (free+buffers+cached) the device has when this
starts to happen more frequently?
Anyway, I don't see what in R&D mode could be affecting memory usage...
Could you isolate it better?

I've never seen this error message.
Does it come from the application or the D-BUS daemon?
What:
cat /proc/sys/fs/file-nr
tells about file descriptor usage in the whole system?
And what:
--------------------------------
for pid in /proc/[0-9]*; do
cmd=$(tr '\0' ' '<$pid/cmdline);
if [ "$cmd" ]; then
echo "$(ls -l $pid/fd/|wc -l) ${cmd%% *}[${pid##*/}]";
fi;
done|sort -n
--------------------------------
lists as number of file descriptors used by the processes?
attached are the results I got when error happens. You can see that
file descriptors are still available.
This is with canolla installed, but canola app itself is not running.
However, there is canola-conf and avahi running.
Seems that the session bus is saturated, launching apps from xterm
(with and without run-standalone.sh) display:
GLIB WARNING ** GConf - Client failed to connect to the D-BUS daemon:
The maximum number of active connections for UID 29999 has been reached
GConf Error: No D-BUS daemon running
Ok, the maximum number error comes from D-BUS. UID 29999 is the "user"
under which all the applications (and some other processes) in the
device are run under. D-BUS seems to be keeping could of connections
per user which in Maemo doesn't make sense, as almost everything is run
as "user" user and almost everything uses D-BUS.
Any hints?
Seems like something does a lot of D-BUS connections.
According to the file descriptor usage, there are not that many
connections open at that moment, so maybe D-BUS counts all connections,
not just active ones in which case e.g. opening and closing D-BUS
connection each time one sends a message would be really bad also
for rest of the applications & system, not just for the performance
of that particular process...
As this problem seems to be Canola related and can happen also after
Canola is uninstalled and device rebooted, does Canola muck up with
D-BUS configuration?
