Re: [Samba] error whit more than one user.
Hi, I'm experiencing a very similar problem: any user except the first one, opens the database at a very very slow transfer rate. The .mdb file size is 75 MB. I've tweaked oplocks with no success If you find any solution please let me know. Thanks in advance, santiago.

[Samba] Samba/LDAP-Backend stability on Debian Sarge
Hi, First, excuse me if this post is a bit offtopic, maybe this should be posted in the debian-users maillist, but I just wanted to read your experiences with this kind of setup, since I've migrated the server to Debian Sarge using LDAP Backend to serve clients using WinXP and Win98, and I've got this serious problems: - Samba segfaults [1] - slapd process crashes very often, almost once per day (i had to create a cron job to restart it periodically). - Slow MS Access database access [2] (I'm still trying to figure this one, maybe is a change of default in some samba option). Any of you is running a setup like this and having similar problems? Any Idea on how I could solve any of this? Thanks, santiago.

Re: [Samba] Slow Access Database on Samba
I've applied all the optimizations you mention in that URL in my own smb.conf but my problem persists. The first user of the database opens it very fast, but the next users that try to open it, do it very slowly. Do you know what option (locking option?) might cause this behaviour? I've also tried 'strict locking = no' with no success. Thanks for your help, santiago.

Re: [Samba] Slow MS Access database after upgrade to Samba3
Thanks for your suggestion, I tried "strict locking = no" with the same results. Any other idea? Thanks, santiago.

[Samba] Slow MS Access database after upgrade to Samba3
Hi, I had a Debian woody server with samba as PDC with LDAP backend in the same box, and mixed windows clients (98, XP, etc). The clients accessed a 75MB MS Access database (.mdb) that was put in a Samba share. Everything was fast... everything was good... But, last week I decided to upgrade to debian Sarge, so as you know Samba was upgraded to Samba3 too (3.0.14a), and now if a user tries to open the database and is the first user accessing it, it opens really fast (100Mps network), but any other user after the first who tries to open it gets the database to open very slow (seems like 10Mbps transfers, as shown in windows network monitor). I've enabled and disabled oplocks with no success at all, but I'm almost sure is some kind of problem with locking, since any other samba transfer between the server and the clients are fast. Have anyone spotted this kind of problem that could give me any advice? Your help is greatly appreciated. I attach most relevant parts of my current smb.conf, dbsystem is the share where the MS Access database is located.
