Hi,
I'm also afflicted with #52. The problem only occurs with system incronjobs, while user incrontabs are not affected.
In
UserTable::OnEvent(…)these type of incronjobs are handled differently. Incrondfork()s and handles the logic in the child process. User incrontabs are invoked by jumping toUserTable::RunAsUser(…)which runs the specified command byexeclp()ing, replacing the child process. System incrontabs' commands are run usingsystem()which is basically anotherfork()and anexecl()– leading to another child process and keeping the first child alive.By replacing
system()withexecl()the first child should be replaced by the desired command and no additional incrond-processes should show up.Please correct me if I'm wrong.
