DESCRIPTION

12       Warnings  that  occur  during  pass 5 (execution) can have a variety of
13       causes.

17       probe insertion errors
18              With any of the systemtap runtimes, it may be possible that  the
19              backends are unable to insert probe points requested by the sys‐
20              temtap script.  For example, you may see errors such as
21
22              WARNING: probe [...] registration error (rc -524)
23
24              (524 is a kernel error code for ENOTSUPP).  These situations are
25              out  of  systemtap's  control, and result in some probes not re‐
26              ceiving any hits.  This may be caused by temporary resource con‐
27              straints or permanent problems.  One common permanent problem is
28              such a probe point being placed at instructions that the runtime
29              (kernel kprobes, uprobes or dyninst) cannot decode or intercept.
30              A possible workaround is to move the probe  points  slightly  in
31              the  script, so as to target a nearby statement, or a caller, or
32              a callee.  See also error::dwarf(7stap).

GATHERING MORE INFORMATION

36       Increasing the verbosity of pass-5 with an option such  as  --vp  00001
37       can help pinpoint the problem.
