OS: Linux

Results from gdb, pmap and output from the replaced plasmashell
SUMMARY
Htop showed that plasmashell process was taking ~79% of all memory on a system
with 64G Ram (62.8G accessible memory), the machine was sluggish as things
started to swap out from memory to disk.
STEPS TO REPRODUCE
1. Unknown, could be related to network that are sometimes a bit unstable
OBSERVED RESULT
After run "plasmashell --replace" (had run it earlier this week, so second time
for the session), I got quite many rows of
[14622:27:0422/225123.533802:ERROR:stun_port.cc(96)] Binding request timed out
from 0.0.0.x:53362 (any)
printed out on the shell for the previous plasmashell process.
EXPECTED RESULT
Retries shouldn't be done until previous request has timed out or kill the
previous request.
