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 sys- temtap runtime, which cleanly terminates the script. If quick termina- tion 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.
