samba - Apr 2001 - Unresponsive samba and 2 gigabyte TDB files, OH MY!

Hello,

I have been tracking this bug as much as possible, and it appears there is a
severe problem in the code that deals with .tdb files. Lately our samba 2.2
testbed has been having painfully slow network responsiveness. It would go
30-60 seconds without a response to a client on many occasions (both
browsing the network, and opening files/refreshing directories). Clients
include Windows 98se, nt, and 2000. When it would "hang" the client
machine's worker thread due to not delivering a timely response, the samba
server would eat 80% cpu time per "working yet buggy" thread. This is
on a
p3-600, 256mb ram, raid1 30gb running OpenBSD Kernel 2.8. Several times it
got so severe the client's explorer would die, and the client pc would have
to be restarted.

Today i found a 2.1 GB brlock.tdb file, a 1.3 GB connections.tdb, and a 1.6
GB locking.tdb file in my lock directory. Samba team, are you aware of this
yet? Searching the mailing lists quickly, it seems one other person has
reported it.

Regards,

Jason Coene

I think the story with this problem is that no-one (other than
yourself and the other correspondent) has been able to reproduce
it.

If you find out any more information you might like to continue
the thread on samba-technical as more samba team members hang out
there rather than this list.
