failed to get session / CdMain: failed to read erros on every boot
Closed this issue · 10 comments
Hello!
On every boot colord.service throws errors like:
colord[1135]: failed to get session [pid 1157]: No such process
colord[1135]: CdMain: failed to read /proc/1157/cmdline
colord[1135]: failed to get session [pid 1099]: No such process
colord[1135]: CdMain: failed to read /proc/1099/cmdline: Failed to open file “/proc/1099/cmdline”: No such file or directory
colord[1135]: failed to get session [pid 1395]: No such process
colord[1135]: CdMain: failed to read /proc/1395/cmdline: Failed to open file “/proc/1395/cmdline”: No such file or directory
colord[1135]: failed to get session [pid 1395]: No such process
colord[1135]: CdMain: failed to read /proc/1395/cmdline: Failed to open file “/proc/1395/cmdline”: No such file or directory
I didn't notice any unusual behavior other than those errors but I think those should be either fixed or reduced it's priority (currently it's warning.
Those errors are already well known elsewhere:

Here's some code analyze: https://bugs.archlinux.org/task/37014#comment131583
Tested on:
colord 1.3.3,1.3.5
Archlinux,debian
colord doesn't support cups exiting on idle. It wasn't something that I knew could happen.
Thank you for the reply. Is it fixable in colord in your opinion?
Sure, but I think this is the kind of thing to discuss on the colord mailing list.
I don't really have anything to add in discussion beside what's in my first post.
@hughsie can you at least hide those messages behind some debug option in order to prevent spam syslog?
@hughsie actually Arch Linux package does contain this commit and it doesn't help:
journalctl -b -u colord
systemd[1]: Starting Manage, Install and Generate Color Profiles...
systemd[1]: Started Manage, Install and Generate Color Profiles.
colord[2011]: CdMain: failed to read /proc/2010/cmdline: Failed to open file “/proc/2010/cmdline”: No such file or directory
colord[2011]: CdMain: failed to read /proc/2010/cmdline: Failed to open file “/proc/2010/cmdline”: No such file or directory
It works partially. The failed to get session [pid xxx]: No such process doesn't occur but above still spams system log. Maybe you could downgrade that message as well.
