Hi, I got the following log messages inside an user mode linux: ,---- | kernel: copy_thread : clone failed - errno = 1 | kernel: flush_thread : new thread failed, errno = 1 | kernel: flush_thread : new thread failed, errno = 1 | kernel: copy_thread : clone failed - errno = 1 `---- No new processes could be started in the uml, but why? Is this a problem with the process limits of the host linux? Regards, Martin
