To all end users experiencing the panic message as mentioned in the topic above.
If you are looking for some relief from these panics then I would highly recommend trying out a -current snapshot. As of a week ago pedro@ had commited what should be a permanent fix for this problem. Now instead of your system panicing, the kernel will try to allocate more memory for additional map entries. The kernel will print ouf the usual uvm_mapent_alloc: out of static map entries but not panic. Also, looking at the vmstat display of systat you will see that "kmapent" has been added to the bottom right corner, this will show you the number of map entries currently in use by the kernel. So, please try this out on any systems which have experienced this panic in the past, and this affects 3.8 too, and post the results back to the list.
