What's the size of your unexpected.tdb file? There seems to be a pathology in vms_tdb.c from the unreclaimed index buckets that result from the cumulative adds and deletes to that file by nmbd.exe. Smbd will search this file sequentially if if misses a datagram it is expecting. Example from an unexpected.tdb that was running 4 days: $ search unexpected.tdb garbagein/log/statistics %SEARCH-S-NOMATCH, STAFF$DISK:[JONESD]UNEXPECTED.TDB;1 - 4 records Files searched: 1 Buffered I/O count: 5 Records searched: 4 Direct I/O count: 752 Characters searched: 952 Page faults: 43 Records matched: 0 Elapsed CPU time: 0 00:00:00.18 Lines printed: 0 Elapsed time: 0 00:00:03.50 %SEARCH-I-NOMATCHES, no strings matched Note that it takes 752 direct I/Os to search 4 records, get a few processes doing this and the latency goes through the roof. The keys for the the records added to unexpected.tdb consists of a 32-bit hash of a timestamp with sequence number which never repeats, so the index buckets fill up with entries for deleted records. I'm still trying to work out the best solution to this problem. One appoach would be to do a convert/reclaim on the file perodically. Another would be to find a way to specify a mask for the hash result (on a per-file basis) so that only a limit number (~couple hundred) key values are used. You could also modify nmbd (the only program that does keyed access) so that the the timestamp cycles every 17 minutes (1024 seconds), limiting your keyspace that way (the expiration logic would need changed to use modulo arithmetic). ---------------------------------------------------------------------------- David L.
