Hi,Since upgrading my DUO to 4.1.7 I have noticed that the DUO is *very* slow to respond SMB/SAMBA network share enumeration requests. It may take up to about a minute for the DUO to provide its list of shares. The problem happens *every* time the DUO is asked to list its shares and not just for the first request. This was not an issue under 4.1.6. (I never ran any of the betas and upgraded from 4.1.6 production directly to 4.1.7 production. There were no obvious issues with the upgrade.)On a client PC this results in about a minute of waiting before the DUO responds with a share list. This is long but not particularly problematic. On the other hand, to my media players this response is *so* long that the media player times out and is no longer able to find the DUO. This is *very* problematic.This is only happening on my DUO with 4.1.7. The same DUO with 4.1.6 was fine and my NVX with 4.2.15 is also fine.Is it possible to get a patch to repair this issue? Is there anything I can do to restore the previously snappy performance? Is it safe/possible to revert to 4.1.6?Regards,Ian.

Hello,I got exactly the same problem with my Duo after ugrade to 4.1.7greetings Berkhout

I've noticed similar behavior on a couple of NV+ units as well on both Win XP & Win 7 clients. Opening up My Computer for the first time with drives mapped to the NAS can take anywhere from 20-30+ seconds.-Randy

I also have noticed slower response. Please note that I had 60 minute spin down timers set before the upgrade to 4.1.7 and continue to have those timers in place.I have drive letters mapped on my vista box. On 4.1.6 when clicking on a network drive letter it was almost immediate, regardless of the spin down timers. Now on 4.1.7 I can wait up to 20 seconds before the contents of the drive are displayed and available to use. Definately something in the 4.1.7 upgrade that is doing this...

Hi,Can one of the Jedis please let us know if this problem is being investigated and how far the investigation has advanced? It would also be helpful if we can have an indication of how long it will take for this to be fixed.With my DUO holding lots of material for my media players I will need to revert firmware if this isn't fixed quickly. (I would welcome advice of any issues reverting from 4.1.7 production back to 4.1.6 production.)By the way, where can we get the 4.1.6 production version of the firmware? It doesn't appear to be available on the ReadyNAS website.Regards,Ian.

I have the same issue. Performance was fine before the 4.1.7 upgrade and now the enumeration is so slow, I cannot mount any filesystems via cifsfs from a Linux box because it times out. Windows is able to perform the mounts, but the initial enumeration is appallingly slow. I'd rather not have to downgrade to 4.1.6, but this problem may force me to do so :(For the record, with is an NV with 1GB of memory and 4 1.5GB Seagate drives.

Actually if anyone here that can replicate the issue has root access that'd be great. If you can increase the logging for samba and try connecting to the share, then send me the resulting logs that might be helpful here.

Been a bit busy here but haven't forgotten about this. fetfer: I have your logs. WSJ: I have your case still and if you have any other logs to add that'd be great. IanSav: I'll keep your contact info in mind here, let me sort through fetfer's data and WSJ's when I get it and if I need more I'll let you know as well.

I've send the file (/var/log/samba/log.smbd)

(mail title: "Case 15187681 - Attn: siigna").
If you need additional information, just let me know.

This SMB network discovery problem is the sole reason I have not upgraded to this version on my Duo. From reading the posts it sounds that I am pretty much guaranteed that I will have this problem.

Does anyone know what the status is on this issue? I feel response from netgear has been extremely slow. I see in the recent posts that some of the logs have finally been obtained by them, but I have not seen any followup discussion by them in this forum.

Any opinions on whether I should upgrade? My current thoughts are no and wait until this is fixed. However, it is taking forever to get a 4.1.8 version where this is fixed and I fear that since the duo is now an older product, there may be no future updates.

Ditto. I'm giving 4.1.7 the swerve until this is resolved, the other benefits of 4.1.7 are just not worth the risk of getting hit by this SMB problem.
