This fixes the infinite loop problem. The VM_METER sysctl is inherently slow because what it does: it iterates over all processes, threads and VM objects. The sysctl(8) output suggests that the totals are computed every five seconds, but in fact this happens when the sysctl is read. *** This bug has been marked as a duplicate of bug 107171 *** -- You are receiving this mail because: You are the assignee for the bug.
