I've encountered a problem at a location where I am using a FreeBSD/Samba setup as a Fileserver for a small LAN ( ~5 workstations ). The hardware spec's of the server should be more than adiquate for a small LAN and the network is running on all 100 base. The problem appears to be initiated by the running of a certain program on several workstaions at once ( Windows 98 workstations ). The way the program works is that it opens serveral ( ~30 ) files on the fileserver at once and uses them as well as storing decent sized database files on the server.. When this program is used on 3 or 4 workstations at once.. eventually all network operations with the server stop working. At first all of the workstations can run the program fine and access all material in the manner expected. After a varying amount of time though eventually one of the workstations will get disconnected from the Samba Fileserver ( the windows drive mapping will disconnect ). At this time the other workstaions on the network may or may not still have access to the server, but as soon at they try to relogin to the server, they are denied ( relogin meaning either rebooting their workstaion, or simple loging off windows and relogining in. ). The message that is given when they try to relogin is "Network Busy". At this point the only remedy that has been found is to reboot the server and it will begin to operate normally for a while. I am wondering if anyone is familiar with a possible cause of this problem. I have had a lot of trouble trying to diagnose the cause.. The possibilities that I have come up with so far are increasing the default max users and NMBCLUSTERS in the freebsd kernel, a new nic ( already tried this once and didn't fix the problem ), the limits on open files.. which should not be it since that are unlimited right now, or a samba configuration problem. I am at a loss as to what the problem is, so if anyone could offer some insight or advice I am eager to hear from you. I do not subscribe to the list, so Please CC me if you think of anything. Kindest Regards, -Aric PS. Just because I mentioned an idea in the possible causes, doesn't mean I know how to fix it, so please, if you have an idea, let me know ; ) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
