Does it cause any problems aside from printing these messages ? What workload do you put on the machine ? The messages came from the failure of the kernel to allocate address space for the kernel stack for a thread being created. Previously, the system would panic encountering this situation. This may happen due to kernel_map address space depletion, for instance, by having a lot (on i386 machines with > 1Gb memory, ~40000) threads.
