Hi all, Apologies if this is the wrong list, or if this has already been reported/fixed. I had trouble finding any related bug reports. I opened a bug at RedHat: https://bugzilla.redhat.com/show_bug.cgi?id=1624029 and the summary is that on our Linux machines (running Scientific Linux kernel versions 3.10.0-693.5.2.el7 and 3.10.0-514.21.1.el7) that connect to a CIFS file system residing on a Hitachi/BlueArc file server, the kernel sometimes neglects to send a "close" request on open file handles if an application is interrupted (with Ctrl-C, and probably also with segfaults as we've seen this with non-interactive processes on our cluster). The result is phantom files (and parent directories) that can't be deleted/moved/renamed because the server thinks there is someone still keeping it open. More details are in the above bug report, including a packet dump and some dmesg output (with debugging output turned on as suggested on wiki.samba.org). Note that the above bug report has been assigned to cifs-utils but I don't think this is a user-space issue. I would appreciate any suggestions on how to address this. Thank you for your help (or redirection)! -syam
