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.
