Bug#773525: Randomly excludes available connections [when there are too many?]
Package: network-manager Version: 0.9.10.0-4 Severity: grave Copypasted from a shell: pietro@debiousci:~$ for i in `seq 1 10`; do nmcli c | wc; done 127 637 12827 127 637 12827 127 627 12827 126 628 12726 127 629 12573 127 634 12828 127 629 12827 127 630 12319 127 631 12827 127 627 12827 I am clearly not changing my list of available connections (so quick!). So what is happening is that network-manager is dropping some of my registered connections, in a random way. Initially I though it is unable to handle more than 127, but then I saw that sometimes it only lists 126. The output of nmcli c is otherwise almost sane (see below). Some connections show up more frequently, some less. Consider for instance: pietro@debiousci:~$ for i in `seq 1 10`; do nmcli c | grep -i condividi; done | sort Condividi 8a006f93-95ac-4683-a683-56413cbb95bb 802-3-ethernet -- Condividi 8a006f93-95ac-4683-a683-56413cbb95bb 802-3-ethernet -- Condividi 8a006f93-95ac-4683-a683-56413cbb95bb 802-3-ethernet -- Condividi cab18fac-376f-42cf-9349-d9b4170dacce 802-3-ethernet -- condividi con dnsmasq d54c2a91-f654-4d52-bdbd-cf9d8efdd9e5 802-3-ethernet -- condividi daa501b5-87eb-4a3f-a6d5-4fa73d042a66 802-3-ethernet -- condividi daa501b5-87eb-4a3f-a6d5-4fa73d042a66 802-3-ethernet -- condividi daa501b5-87eb-4a3f-a6d5-4fa73d042a66 802-3-ethernet -- condividi daa501b5-87eb-4a3f-a6d5-4fa73d042a66 802-3-ethernet -- condividi daa501b5-87eb-4a3f-a6d5-4fa73d042a66 802-3-ethernet -- condividi daa501b5-87eb-4a3f-a6d5-4fa73d042a66 802-3-ethernet -- condividi daa501b5-87eb-4a3f-a6d5-4fa73d042a66 802-3-ethernet -- condividi daa501b5-87eb-4a3f-a6d5-4fa73d042a66 802-3-ethernet -- condividi daa501b5-87eb-4a3f-a6d5-4fa73d042a66 802-3-ethernet -- So - one connection, Condividi, is shown 3 times out of 10 - one connection, condividi con dnsmasq, is shown 1 time only - one connection, condividi, is shown most of the times... with different space paddings Different runs of the above command will clearly give different results, but some connections are indeed more rare - i.e. condividi con dnsmasq usually shows in none of the 10 tries - and some exhibit (even more than 2) different space paddings. The wireless connection I need to use at work shows up more or less once every 100 tries. Which, by the way, is very annoying: it usually disables autoconnect, makes it virtually impossible to use gnome-control-center (or the GNOME 3 drop-down menu) to connect, and makes it very hard and time consuming also with nmcli c up (nm-connection-editor is also affected). This is why the bug is grave: in particular, if a remote server relies on network-manager in order to connect at startup... you'd better hope it is not too remote. The bug was present also with 0.9.10.0-3. My rough guess is that the problematic upgrade was located between July and September.

Not really, grave means, the package is unusable, which it clearly i'snt. The bug was present also with 0.9.10.0-3. My rough guess is that the problematic upgrade was located between July and September. Can you pinpoint the exact version please. pietro@debiousci:~$ ls /etc/NetworkManager/system-connections | wc 431 8918594 How did you generate 431 connections?
