--- Comment #1 from Frank Ch. Eigler <fche at redhat dot com> ---
Consider trying the probe-by-buildid mechanism added recently:

    probe process("deadbeefdeadbeef").FOO { }
instead of
    probe process("/path/to/binary").FOO { }

... where deadbeef is simply the hexadecimal buildid for the target binary,=
 as
printed by "file" or "readelf -n".

Your RHEL7 version of stap is much too old for that, but maybe you can get =
hold
of RH DTS builds, or build your own from upstream sources / RPMs, this shou=
ld
work.

Otherwise, yeah, path name based matching is known to be difficult when the=
re
are many names for the same binary, and from different containers' points of
view.
