Number of reports (regardless whether they contain warnings or errors) that has to be reached by a process before aborting the application. 0 disables the limit. Just as with CHECK-MAX-ERRORS, this is a per-process counter.
It is disabled by default because the CHECK-SUPPRESSION-LIMIT setting already ensures that each type of error or warning is only reported a limited number of times. Setting CHECK-MAX-REPORTS would help to automatically shut down the application, if that is desired.
