When we try to print PDF documents (as well as other types), we experience a buffer overflow. I've attached a level 10 log level.
basically, I get

I dunno what this is a network trace is needed too.
SAMBA BUG REPORTING
This is a small howto to help you to provide all information which are needed
to find out what's going on your machine. This is a general howto so maybe it
will cover more things you don't use.
Please also read http://www.chiark.greenend.org.uk/~sgtatham/bugs
Providing instructions how the reproduce the error
The first aim of a bug report is to let the developer see the failure with
their own eyes. If you can't be with them to make it fail in front of them,
give them detailed instructions how to reproduce the problem so that they can
reproduce the error on their development environment.
If this doesn't work, describe everything in detail! The more information you
provide the easier we can see what's going on.
Providing Samba log files
Post the output of 'rpm -qi samba' or 'rpm -qi samba-<subpackage>' if you're on
a RPM based system. It gives detailed information about the installed packages.
We need that information to reconstruct what happened and possibly to reproduce
the bug on our machines.
Always provide all log files from the '/var/log/samba/' directory and the
configuration file '/etc/samba/smb.conf'! If you see errors in tdb files make
sure you add the related tdb files from '/var/lib/samba'.
If winbind for logging in is part of the problem please provide
'/etc/security/pam_winbind.conf' and if you have enabled debug in
'pam_winbind.conf' '/var/log/messages' or '/var/log/secure' is required too.
More detailed description about different Samba components can be found below
If you discover a crash in one of the Samba components, please make sure that
you have installed debuginfo packages. Often the backtrace can be found in the
log files. If you have installed debuginfo packages, you can find a short
backtrace in the log files and a few lines later the full backtrace. Make sure
you provide the full backtrace.
Testing daemons (winbind, smb, nmb)
1. Stop all running Samba processes (winbind, smb, nmb)
2. Remove all log files from /var/log/samba/
With this approach we ensure to have the start date of the testing in the
3. Edit /etc/samba/smb.conf and set the following variables in the in the
[general] section of the config:
debug level = 10
debug pid = true
max log size = 0
Instead of setting a global debug level in smb.conf it's also visible to
smbcontrol <damon_name> debug 10
to increase the debug level of the Samba daemon in question to 10 at run
If winbind is part of the scenario edit /etc/security/pam_winbind.conf
debug = yes
4. Start the processes again (winbind, smb, nmb)
5. Reproduce the error and note the time when you start any test. If a problem
occurs while testing note the time (use date on the system you perform the
tests on to get a time fitting to the log files).
Attach the log files from '/var/log/samba/' and the tdb files from
'/var/lib/samba/' to the bug. If possible, remove the tdb files and provide clean
files. Therefore it's best to bond them to one compressed tar archive. The
relevant parts of '/var/log/messages' could be interesting too.
If possible create network traces with tcpdump or wireshark from the problem and
attach them too. Always make sure to capture only one problem per network trace
file. This makes it easier to understand the problem.
tcpdump -n -i eth0 -s 0 -w samba-problem-description.pcap
If you have a special network setup especially with Active Domain controllers
please describe how you're network looks like and what the domain names are.
Tell us which version of Windows you're using and which functional level of AD.

Thanks for the report Tom. Could you please attach the level 10 log to the bug directly. The URL provided is no longer reachable.
