[Message part 1 (text/plain, inline)]

I am just using emacs normally, mostly for typescript development, so
that might be the offending mode. Emacs is currently using 1.7GB of
memory, the other day I killed it after I saw it was using 19.9GB. I ran
memory report and nothing was reported as using significant memory.

It could be that a large part of memory that is mapped into the Emacs
process is actually free, and glibc keeps it because it cannot release
it to the system for some reason.

When you get a significantly larger memory footprint again, please
invoke the function 'malloc-info', and post here everything it writes
to stderr stream.  The data this produces will show how much memory is
actually in use.

Thanks.

Ryan, it seems like we need more information here to make any progress.

Are you still seeing this?  If yes, did you have a chance to look into
this any further?

More information was requested, but none was given within 4 months, so
I'm closing this bug.  If this is still an issue, please reply to this
email (use "Reply to all" in your email client) and we can reopen the
bug report.
