Hi Dave, Quick comments from me: - sorry about not appreciating that the new location of the LDM queue is on a file system that is not NFS exported - the reason Steve asked you to move the queue was we saw that rpc.ldmd process "hangs" were being caused by a wait on a system call (fcntl) that asks for a lock on a region of the LDM queue (one needs to lock the region of the queue that a new product will be written to before doing the write). Our grasping at straws comment was our hopes that the waiting for the system to grant the lock was somehow related to the partition being NFS exported. Since you experienced the problem yesterday afternoon after the queue was moved, it is not likely that the NFS export was the cause of the problem. Unless Steve has new ideas, we are down to there being a bug in the operating system -- not a good situation at all!
