[Pkg-utopia-maintainers] Bug#781007: network-manager has an 128 max connections limit

[Faidon Liambotis]

Package: network-manager
Version: 0.9.10.0-6
Severity: important

OK, this may sound weird but...

I have noticed some odd behavior, with Network Manager not showing one
of my GSM providers on the tray icon at random. Then today, I wanted to
edit one of my connections to change the DNS server list and hit "Edit
connections" (which spawns nm-connection-editor) and could not find it.

Repeated invocations of nm-connection-editor showed different
connections being listed -- I even got the connection I wanted at some
point. I initially thought it was an NM GUI bug, so I tried both nmtui
and nmcli and the same thing happened: every time I called them I could
see a list of connections but somewhat different every time.

Then... I thought of counting them: it seems that "nmcli c |wc -l"
consistently reports back "129" (header line + 128 connections). Saving
+ diffing the output, though, seems to indicate that I get a different
list of 128 saved connections every time I call it (I have lots of them
as this includes a lot of random hotspots I've picked up while
travelling).

This is quite an annoying limitation and manifests quite badly in a hard
to debug way. I could see this being triaged as serious as well -- the
only reason I didn't is that probably not a lot of people have > 128
connections saved.

I'd prefer if I didn't list my connections here for privacy reasons, but
do let me know if there's anything you want to run on the system itself
for debugging purposes.

Thanks,
Faidon
