Either you "ulimit"ed your UML's (and one UML needs a lot o= f=20 filehandles) or you need to increase the filehandle limit where it is=20 happening. > This error appears first after a few hours of running and the boxes > with this error is no longer reachable. *Very* strange. If you mean that you can no longer login / do anything that= =20 needs to create a new process inside UML, I understand it. Otherwise, there= =20 is something strange. Please try to watch how many open files UML has (ls=20 /proc//fd is your friend) and increase filehandles and process limi= ts=20 (read man proc and search about /proc/sys/kernel for this). > The following other errors > also appear: > > flush_thread : new thread failed, errno =3D 1 > copy_thread : clone failed - errno =3D 11 > copy_thread : clone failed - errno =3D 1 > copy_thread : clone failed - errno =3D 1 EPERM (very strange) and EAGAIN (too many processes running). Checking the = source for sys_clone could be needed to diagnose EPERM (unless you have=20 something as GrSecurity active). --=20 Paolo Giarrusso, aka Blaisorblade Linux registered user n. 292729 ------------------------------------------------------- SF.Net is sponsored by: Speed Start Your Linux Apps Now.
