ERROR::PASS5(7stap) ERROR::PASS5(7stap)
warning::pass5 - systemtap pass-5 warnings
Warnings that occur during pass 5 (execution) can have a variety
of causes.
probe insertion errors
With any of the systemtap runtimes, it may be possible
that the backends are unable to insert probe points
requested by the systemtap script. For example, you may
see errors such as
WARNING: probe [...] registration error (rc -524)
(524 is a kernel error code for ENOTSUPP). These
situations are out of systemtap's control, and result in
some probes not receiving any hits. This may be caused by
temporary resource constraints or permanent problems. One
common permanent problem is such a probe point being
placed at instructions that the runtime (kernel kprobes,
uprobes or dyninst) cannot decode or intercept. A
possible workaround is to move the probe points slightly
in the script, so as to target a nearby statement, or a
caller, or a callee. See also error::dwarf(7stap).
Increasing the verbosity of pass-5 with an option such as --vp
00001 can help pinpoint the problem.
