Please help.

error::pass5
ERROR::PASS5(7stap) ERROR::PASS5(7stap)
NAME
error::pass5 - systemtap pass-5 errors
DESCRIPTION
Errors that occur during pass 5 (execution) can have a variety of causes.
exceptional events during script execution
The systemtap translator and runtime include numerous error checks that aim to protect the systems and the users from mistakes or
transient conditions. The script may deliberately call the error() tapset function to signal a problem. Some memory needed for
accessing $context variables may be temporarily unavailable. Consider using the try/catch construct to wrap script fragments in
exception-handling code. Consider using the stap --suppress-handler-errors or stap --skip-badvars option.
resource exhaustion
One of several types of space or time resource limits may be exceeded by the script, including system overload, too many tuples to
be stored in an array, etc. Some of the error messages identify the constraint by macro name, which may be individually raised.
Consider using the stap --suppress-handler-errors option. Extend or disable resource limits using the stap -DLIMIT=NNNN option.
remote execution server problems
If you use the stap --remote option to direct a systemtap script to be executed somewhere else, ensure that an SSH connection may be
made to the remote host, and that it has the current systemtap runtime installed & available.
installation/permission problems
It is possible that your installation of systemtap was not correctly installed. For example, the /usr/bin/staprun program may lack
the necessary setuid permissions, or your invoking userid might not have sufficient privileges (root, or stapusr and related group
memberships). Environment variables may interfere with locating /usr/libexec/.../stapio.
errors from target program
The program invoked by the stap -c CMD option may exit with a non-zero code.
uncaught exceptions in the target program
When using --runtime=dyninst you may encounter an issue where the target program aborts with a message like "terminate called after
throwing an instance of 'foo_exception'". This is unfortunately a limitation of Dyninst, which sometimes prevents exceptions from
properly unwinding through instrumented code.
GATHERING MORE INFORMATION
Increasing the verbosity of pass-5 with an option such as --vp 00001 can help pinpoint the problem.
