I have the following setup:
Compaq Proliant 6000 w/ 4 cpu's, 512 MB ram
SuSE PRO 8.0
samba 2.2.5 w/winbind
using ACL's (acl-2.0.11-2)
Using samba to provide access to a share using MS NT server for
authentication via winbind. All works well until the following occurs:
I am getting the following errors showing in my messages file ( and also
using dmesg):
<1>Unable to handle kernel NULL pointer dereference at virtual address
0000002d
printing eip:

At some point the machine crashes with an entry as above and the only
way to recover is to do a hard shutdown (ouch!)
If any additional info is needed please let me know.

As a userspace app, Samba should never be able to cause such a condition.

You need to fix this before looking at any other Samba issues. Jeremy.
>At some point the machine crashes with an entry >as above and the only way to recover is to do a >hard shutdown (ouch!)Since it is a multiprocessor industry-grade server you are using, my tip might be irrelevant for your case but here we go anyways: smbd activities crashed my Siemens-Fujitsu P4/2GHz i845 chipset reliably though at unpredictable intervals between a couple of hours and a full day and a half until I reinstalled my SuSE 8.1 on a SCSI disk. The IDE DMA in some chipsets has a quirk which is not properly accounted for, in kernel 2.4.19 for example, leading instead to kernel panic and system freeze (sometimes caps-lock and scroll-lock LEDs blink when it happens but not always). If your system disk is SCSI to begin with then you can ignore my posting. _____________________________________________________________ Get 25MB, POP3, Spam Filtering with LYCOS MAIL PLUS for $19.95/year. http://login.mail.lycos.com/brandPage.shtml?pageId=plus&ref=lmtplus
