I >think that many problems just don't appear beaause machines are not loaded. I've seen this problem with mmap and INN too. Basically, the active file wasn't staying current, and the hi index value was dropping behind, causing "cant symlink" errors. I believe the problem is related to swapping. On heavy swapping systems, it will happen a lot. It appears that when the mmap'ed active is paged out, sometimes it isn't written back to the file, but when it is paged in, it is read back from the file. Tom
