We are seeing occasional file corruptions on files that haven't changed in ages. The file corruption has been at some random offset within files and contains text that looks like it should be in the samba log. Here's the contents of a Windows .bat file after the corruption has taken place. The first three lines look intact but then there is the corruption: @ECHO OFF SET MAKE_MODE=UNIX bash --login [2000/10/11 09:22:44, 0] rpc_client/cli_netlogon.c:cli_net_sam_logon(391) cli_net_sam_logon: NT_STATUS_NO_SUCH_USER [2000/10/11 09:22:44, 0] smbd/password.c:domain_client_validate(1470) domain_client_validate: unable to validate password for user smsclitoknacct& in domain JOHNS to Domain controller MAIN.
