I’m running Legato on a Yocto 2.2.1 linux build (a generic x86 machine using kernel 4.8.12, with support for Smack and cgroup compiled into the kernel). It runs for about fifteen seconds and then crashes the kernel, forcing the machine to reboot.
I get three of these “timed out” messages when the framework starts up.
Legato: -WRN- | UNKNOWN/framework T=main | LE_FILENAME DAEMON_DAEMONIZE() 71 | Timed out out after waiting 5000 ms for indication from child.
Then several seconds later I get this, followed by an immediate reboot:
Legato: CRT | UNKNOWN/framework T=main | LE_FILENAME TryToRun() 1050 | Supervisor was killed by a signal 14.
There are no core files or log files left behind that I can find. The only way I got these log lines was by capturing it on video. True story.
Also, during those several seconds between the timeouts and the killed supervisor, I have tried running Legato’s log utility and other tools, but none of them work at all. The command will just hang until the system reboot.
Any clues as to where I should look?
