If it is 1280 1MB pages, I need to increase limit. Looks like setting both max_wired and limit to 1.5GB helps, thank you! > > Ooops, no, it doesn't help. It only postponed problem :-( Looks like I need to report this problem to upstream as new one. Maybe it needs much more memory to mlock(). I used these settings for sysutils/memtester to be able to mlock() and test most part of newly installed physical RAM, so I used to raise it upto 80% of total 2GB RAM and was able successfully run memtester within X session without any adverse effects. I mean, try incresing it more.
