The ~ symbols are C braindamage. Ignore them, also the leading _ on C externals. The double calls to mch/mch indicate a fault in kernel mode; the handler goes through them to prf. The rl calling lp indicates gross lossage; investiaget there for bugs. The problem with the system wedging is probably buffer starvation; the system takes one block buffer for each mounted FS and when you get a lot of FS's mounted the size of the buffer-pool is appreciably smaller, leading to deadlocks. If any of this was unbearably terse, let me know and I'll explain at length. ------- --------------- This blew up when I sent it yesterday... -------
