https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=231457 --- Comment #12 from dimka@dz.dn.ua --- I check and made sure that 12.0-RELEASE/amd64 is also affected by this problem, test tool and sendmail processes was killed by OOM after physical memory is over and several megabytes of swap were used. Short hardware details: CPU: Intel(R) Celeron(R) CPU 847 @ 1.10GHz (1097.53-MHz K8-class CPU) real memory = 2147483648 (2048 MB) avail memory = 1987403776 (1895 MB) FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs FreeBSD/SMP: 1 package(s) x 2 core(s) da0: <SanDisk Ultra USB 3.0 1.00> Removable Direct Access SPC-4 SCSI device da0: 14663MB (30031250 512 byte sectors) You can a very simple test on your hardware or VM: 1. Install system from DVD to cleaned drive in "Auto (ZFS)" mode. 2. Comment GPT swap entry (created by installer) in /etc/fstab. 3. Create swap space on ZFS pool: # zfs create -V 8GB -o org.freebsd:swap=on zroot/swap 4. Reboot. 5. Compile and use "Memory occupation test tool" from bug report attachments: # ./memphage 9500 Argument is memory occupation limit (mem free + swap free - 500) in megabytes. -- You are receiving this mail because: You are the assignee for the bug.
