Bug ID: 383959
Summary: memory leak when connecting to chip
Product: plasma-nm
Version: 5.10.4
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: applet
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
When connecting a chip board via USB (similar to RaspPI ->
https://getchip.com/), plasma-nm continues to try connecting to it, and gets
stuck on acquiring network address.
It never gets a network address (and I don't want it to, I just want to power
it, or e.g. flash it) , however the plasma-nm applet becomes non-responsive. In
this case, plasmashell is consuming all the memory and eventually all the swap
on the machine, and eventually plasmashell gets killed by the OOM.
Each time I plug in one of these devices it shows up as a new wired connection,
so I cannot get plasma-nm to remember the device settings and disable the
connection.
The USB dmesg output is as follows:
[121719.097187] usb 3-7.2: new high-speed USB device number 13 using xhci_hcd
