We have again encountered a nasty and weird problem with UML. If swap is enabled for a virtual machine, and the virtual machine actually swaps something, swapoff at shutdown hangs the machine. Now, I could understand this, if it was because the running processes would not fit in main memory without swap, but this happens even though all other processes have been killed - just init and the script running swapoff remains. There's plenty of free memory, but some 500kB of swap in use. The swap is a disk file, entirely non-sparse. We are running 2.6.9-bs5.
We also had a similar problem earlier (exact same symptoms) - but we came to the conclusion then that if devfsd was running, swapoff hung. Problem was solved by removing devfsd entirely (we thought it might have to do with the locking of pages that devfs does), but now it resurfaced again, and there doesn't seem to be any process left to blame this time. Yet again, we are investigating this further - if anyone has any ideas, please give a holler. -- Naked ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
