My prior kernel was built on 24-Jul. If there is not sufficient memory available to reload the system (4 Meg.), the resume fails with a message that memory was exhausted. Usually I can try resuming again and it will work. Sometimes I get the error two or three times before the system resumes. Since I have not touched VirtualBox other than to rebuild the kmod after the kernel build, it looks like something in the OS triggered this. Since the system frees up some memory each time so that the VM eventually resumes, it looks like the memory request is made to the OS, but VB is not waiting or not enough memory is freed to allow the VB to complete the resume. Any clue what might have changed over those 13 days? I am running GENERIC except that I run the 4BSD scheduler. -- Kevin Oberman, Part time kid herder and retired Network Engineer E-mail: rkoberman@gmail.com PGP Fingerprint: D03FB98AFA78E3B78C1694B318AB39EF1B055683
