NAME

       error::fault - memory access faults

DESCRIPTION

       Read  or  write faults can occur during the operation of a systemtap script, if the script
       causes dereferencing of a pointer that turns out to be invalid.  This  can  be  caused  by
       using  context variables that do not happen to have valid values, or perhaps references to
       memory that is unavailable at that moment due to paging.

       These fault conditions are benign because they are caught by the systemtap runtime,  which
       cleanly  terminates  the  script.  If quick termination is not desired, consider using the
       --suppress-handler-errors or -DMAXERRORS=NN stap options, or wrapping  relevant  parts  of
       the probe handlers in a try/catch block.
