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 mis‐
	      takes 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 mes‐
	      sages identify the constraint by macro name, which may be	 indi‐
	      vidually	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 system‐
	      tap runtime installed & available.

       installation/permission problems
	      It is possible that your installation of systemtap was not  cor‐
	      rectly 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	unfor‐
	      tunately	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.
