Actually it's not the "top" of the output that's interesting. The snapshot #1 just shows where memory went initially on start-up (to loading images). That doesn't represent the ongoing growth problem though. You need to scroll down to later snapshots in the ms_print output to see where the growth is coming from, like snapshot 51:

/usr/lib/libgjs.so.0.0.0 /usr/lib/x86_64-linux-gnu/libmozjs-52.so.0.0.0 Which sounds like it's getting closer to the core of the problem. -- You received this bug notification because you are a member
