Hi,

I havn't changed my samba configuation recently, (but have been playing around with my network config), and have been getting a smbd crash on browsing large directories, this is what is printed in the log file:

Any ideas on what could be wrong? I was using the x86 version of samba, but upgraded to the ~x86 version (3.2.14).

Thanks
