Too many Windows clients?
I am having a problem w/ one machine that is running ReadyOS 6.9.3. It is legacy hardware. I have upgraded the RAM to 2GB. My problem is that occasionally windows SMB clients lose connections and can't reconnect. If I try to open a connection to the NAS from the file explorer on any given windows client, I get a password prompt that fails. I have to reboot the NAS to clear this.
There is a lot I don't know about windows/samba networking, both in general and specifically with these machines, so I have some really basic questions.
- What is the limit on windows clients?
- How are client connections counted and/or how do they use samba resources? For example, I have about 10 machines that use this NAS, but each machine might have several shortcuts to files on this server, and periodically open multiple files on the server, including dlls, .exes, and text files. So on one machine, if I have 5 shortcuts and I have 5 files open, is this 10 connections Or 5? Or 1? Or if on a client I am running 3 .exes that utilize 5 different dlls on the NAS, how is this counted and use resources?
Is there a way I can get a count of the number of active client connections?
Where do I look for evidence as to what is happening? In the past I have looked in windbind.log, and found what looked like a smoking gun - messages that it couldn't fork, couldn't allocate memory. However, this time I looked, and did not see these messages.

Hi zeke561
Regarding limit, there shouldn't be any, it is more of how the resources are being accessed or used, since you mentioned that you have multiple clients accessing a resource all at the same time and the NAS doing services as well that uses your NAS memory but there are also other possible underlying issues that may cause this. Like authentication and other service that might need information from your users/AD.
Do you have specific time and date that the issue occurs? We can then track it from the logs.
You can try disabling quotas on the volume as a start.

Hi Marc_V
In the second set of logs that I sent, the problem was occuring ca. 8am on 5/1/2018. I was getting errors in winbind.log, and pam.log (at least). I was not having problems getting AD authentication w/ other machines, including a couple other Readynas machines. The problem cleared up as soon as I rebooted the machine exhibiting the problems. If I understand what I'm reading, smbstatus.log shows a bunch of files that are locked with "DENY_WRITE" property. This includes some directories, which I don't understand.
