Hi,
I have just switched from FreeBSD 4.11 using 3.0.21b to NetBSD 3.0.1
using 3.0.22. With the same configuration, and the same clients, I am
now seeing what appears to be some rather large memory leakage [ I am
not sure if this is the fault of Samba or NetBSD ]. Eventually the
process will run out of memory (machine only has 256MB of RAM) and the
Windows clients (2000, SP4 and all the latest updates) pop up a message:
"Insufficient system resources exist to complete the requested service"
At which point the Samba server becomes unresponsive to the current user
logged in. At the same time, I am seeing alot of errors in the logs
regarding memory allocation errors:

The smbd process memory usage according to `top` at this time:
---
28795 admin 2 0 130M 58M select 5:31 0.00% 0.00% smbd
---
I never had this problem with FreeBSD 4.11 and 3.0.21b. Another user
logged in is currently sitting at:
---
10090 donna 2 0 52M 2704K select 3:25 0.00% 0.00% smbd
---
I have logged back on and I am instantly seeing:
---
25971 admin 2 0 24M 4040K select 0:22 0.00% 0.00% smbd
---
Something doesn't seem quite right here!
I'm not sure what kind of info you need, but I have attached my smb.conf
(it's a bit messy, perhaps this issue is just a misconfiguration
somewhere?) to get started. If anything else is required (it didn't dump
a core so I have no backtrace or anything) I will try my best to provide it.
