Syntax: choose from drop down list
Upper limit to memory size of walker processes. If a walker process exceeds this limit, it is re-started (at the same point it left off) by the dispatcher, at most once. If the same child repeatedly exceeds this limit, the walk may stop until it is re-started via schedule or manually. Note that this is a soft, not hard limit: the process may exceed it briefly, yet will exit gracefully and not crash if so.
