We've been pulling our hair out of our heads trying to 
figure out what could be causing the leak :-).

We have a case open with JTAC, but they have us trending 
memory usage over a number of days, it's running slow. 
Refreshing to hear someone else has seen this in the field.

We haven't gotten this far, although we've seen an average 
increase of CPU usage by at least 3% daily on M7i's running 
with 1.5GB of DRAM on RE-850's.

We're quite surprised Juniper could have missed this, if it 
is indeed a bug, as we are easily seeing this issue on a 
new, fully-configured box not plugged into the network, just 
running some burn tests - and memory usage creeps up slowly, 
day by day.

Not loving 9.4R1.8 so far...

Which is our IGP.

Trying to search these up isn't turning up anything. Are 
they public?

Cheers,

Mark.
