I thought that I saw some correlation between some activity on = the system and increases in missing pages. But I was never able to reproduce t= he leak at will, so not sure if my observation was actually valid. Just in case, it appeared to me that the leak was correlated with an application written in Go. I suspected that it used some compatibility sys= tem calls (especially related to mmap) and there was a bug somewhere in the com= pat code. --=20 You are receiving this mail because: You are the assignee for the bug.=
