Continous Samba crash (Lock order violation)

[Naslex]

After installing a newer version of Nas4free (10.2.0.2.2003) I have some serious problems with my Samba shares. From some VM's (Debian and CentOS) the shares are not working correctly in the sense that I cannot delete files and moving seems an issue also.

In the log I can see that the SMBD process is crashing every 10 seconds with the crashlog as shown below.

When I downgrade to version 10.2.0.2.1868 the problems disappear. Does anyone have any suggestion to fix this problem?

Many thanks in advance,

Lex
