[Bug 1094438] Re: Samba crashes invalid pointer: 0x00007f0bc3de7590

[Dave Gilbert]

It would be better if you could upload this bug info with apport-collect
and that will get a full set of diagnostic logs.

You might also want to install the -dbgsym package (
https://wiki.ubuntu.com/DebuggingProgramCrash ) that will get a much
more detailed backtrace if you can't upload the crash logs directly.

Title:
  Samba crashes invalid pointer: 0x00007f0bc3de7590

Status in “samba” package in Ubuntu:
  New

Bug description:
  Ubuntu 12.04.1 LTS
  Samba 2:3.6.3-2ubuntu2.3
  krb5-config 2.2
  Samba on ubuntu joined to Windows 2003 domain
  Share on /media/100RAGE = /dev/md0 (software raid5)

  getent passwd, getent group working fine.
  All working fine, except I see errors in samba logs.

  We have two of the same server with the same configuration (differents
  only in hostname).

  Samba crushes everytime after opening shared folder from windows
  workstation on both servers.
