Raspberry Pi VM tests

Asked by 1 year ago
I did some testing to see if I could reproduce the strange killed processes which I experienced during build world on my 256MB RPI. I disabled the swap partition on my USB drive and did some testing with the "stress" program from ports: stress --vm 1 --vm-bytes 200M --vm-keep results in dmesg: pid 664 (stress), uid 1000, was killed: out of swap space That's logical. Next I did a stress --vm 1 --vm-bytes 150M --vm-keep and a few moments later: pid 606 (sshd), uid 0: exited on signal 11 pid 610 (cron), uid 0: exited on signal 11 (core dumped) This should NOT happen. Another problem is that i tried a large zmodem upload on the serial console of a 10MB file. Minicom and sz on the sending site, rz (from lrzsz from ports) on the receiving site. This works, but if I run a compile in another ssh session during the transfer then the transfer hangs and the serial console will no longer handle any input. Killing the console shell results in a new getty but it cannot receive any input. It's dead. data > /dev/console does show output however. I use a kernel from a current tree a few days old. Can others reproduce these problems?
