I've been running a linux fileserver here at work for about a year now and have had no troubles with it until about 2 months ago when a permesions error prevented me from accessing any account, even root. At the time it was easier to just wipe linux off and reinstall, but now I'm having some really nasty problems. We do a lot of database work with databases in the 100-100,000 record range. These are handled by a windows program, but the samba client seems to disagree with it... for one the databases often fail to close the files, thus leaving locks on files not actually open, but more importantly I've been haaving some form of memmory leak. I've got about a gig of RAM in my server, but no matter if I reset the samba client, kill it or anything else, I always end up with about 5.2 meg free space after only a day or so. Now I know your going to need more info then this but I'm not sure what info to post exactly, so if you can let me know any suggestions, or what info you may need I would appreciate it.

If you are talking about free RAM on the Linux server (from a program like top), then that can be normal. Linux uses free RAM for cache and will use all the RAM, so you will show no RAM left ... cache will be deallocated and used as RAM as required.

What distrubution of linux are you using?

Are your connections from the windows machines on a fast LAN or are some of the windows clients located on a slower external network?

Hey another Cat's Fan! No all the clients connecting are on 100 Mbit switched network. I'm using Mandrake 9.0 distro. Below is my samba.conf file.

# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options (perhaps too
# many!) most of which are not shown in this example
# Any line which starts with a ; (semi-colon) or a # (hash)
# is a comment and is ignored. In this example we will use a #
# for commentry and a ; for parts of the config file that you
# may wish to enable
# NOTE: Whenever you modify this file you should run the command "testparm"
# to check that you have not made any basic syntactic errors.
