For me it is spamass-milter. On an amd64, 10.0, 56 days up: PID USERNAME PRI NICE SIZE RES STATE TIME WCPU CPU COMMAND 387 root 85 0 26G 236M poll/0 0:50 0.00% 0.00% spamass-mil On amd64 a vsize of 26G is only nasty, on my i386 mail server the milter dies every few days at ~2G :-) I have a small test (p2.c, attached) that shows the leak. It is always a combination of pthread_create()/pthread_detach(). Using pthread_join() instead of pthread_detach() doesn't have the problem. All started with this commit: https://mail-index.netbsd.org/source-changes/2020/01/27/msg113341.html Undoing part of this commit (diff attached) makes the leak disappear for me. I'm not sure if this is fix or it just plasters another bug, I'm not very familiar with the lwp lifecycle. At least I'm sure pthread__deadqueue fills with dead pthreads and the mapped stacks are the memory leak observed. -- J. Hannken-Illjes - hann...@mailbox.org
