If you see a process in RWMPB state, what does this generally mean?

RWMPB is Resource Wait Modify Page writer Busy. RWMPB is a state, processes may be placed in, while waiting for the modified page writer to write the Modified Page List (MPL) to the pagefile. When the number of pages on the modified pagelist exceeds the SYSGEN parameter value for MPW_WAITLIMIT, any process adding pages to the MPL will enter this state, which generally means:

  • The processes working set is full (i.e. another page must be removed before the required page can be faulted in)
  • The page to be removed would be going onto the modified list
