--- Comment #10 from Amar Tumballi <atumball at redhat.com> ---
Something unrelated to the issue here:

I noticed below snippet in statedump:
----
[mount/fuse.fuse - usage-type gf_fuse_mt_iov_base memusage]
size=3434686672
num_allocs=1
max_size=4294962768
max_num_allocs=19
total_allocs=66157424
----

This was result of 32bit overflow in getting size and max_size... Made me look
at wrong place, and search fuse-bridge for leak for more than 20mins just by
looking at such a huge usage report.. Needs to be fixed for sure.

I see from valgrind report that SSL is enabled in the setup, so, not sure if
that causes the issue. Wasn't able to pin-point at the leak by looking at the
reports. Will keep this bug updated!
