Hello, If maui is started via init script, it outputs the following error to the console: # rc-config start maui Starting init script maui | * Starting Maui scheduler ... maui |cannot set process group: Operation not permitted [ ok ] | And maui.log shows: 05/06 01:29:19 ServerDemonize() 05/06 01:29:19 ERROR: cannot setpgrp, errno: 1 (Operation not permitted) 05/06 01:29:19 INFO: parent is exiting 05/06 01:29:19 INFO: child process in background If maui is started from the shell as: # maui There are no error messages in both console and maui.log file. If # start-stop-daemon maui is used from the console, error appear again in the same way. My openrc version is 0.9.9.3.

Same behavior on my clusters. I thinks it's not a Gentoo || OpenRC problems at all. Problem inside maui itself. They use setpgrp call when maui-process (before fork) already session leader when it was started by start-stop-daemon. See small example: #include <sys/types.h> #include <unistd.h> #include <stdio.h> int main(int argc, char* argv[]) { pid_t sid = getsid(0); pid_t pgid = getpgid(0); pid_t pid = getpid(); printf("Session ID = %i\n", sid); printf("\tGroup ID = %i\n", pgid); printf("\t\tProcess ID = %i\n", pid); if (setpgrp() == -1) { perror("setpgrp failed"); return 1; } return 0; } myhost maui.problem # ./a.out Session ID = 36627 <--- (my bash session here) Group ID = 46152 Process ID = 46152 myhost maui.problem # start-stop-daemon --exec ./a.out Session ID = 46154 Group ID = 46154 Process ID = 46154 setpgrp failed: Operation not permitted * start-stop-daemon: failed to start `./a.out' I think it is safe to comment these lines in OServer.c source code for modern kernel & openrc versions. Parent-Maui-process is session and group leader by the system conditions. Or just ignore this error.
