All servers spec'ed like = this have the same identical problem and it is not a hardware issue = because all memory tests have been negative. basically the issue comes after PAE kernel has been compiled and = the system outputs all the time the following: cannot fork kstack allocation failed or vm_thread_new: kstack = allocation failed Since, this is a dell server there is basically nothing that I = can disable in BIOS, so perhaps someone knows what loader options do I = need to tweak the kernel and stop this from happening. Thanks, Dennis=
