Creating new file on CIFS file share blocks for 30 seconds

Symptoms

Creating a new file on CIFS (Samba) file share blocks the operation and the system for 30 seconds before finishing. Other file operations and malware detection work normally. Only the CIFS clients that mount the file share are affected. The CIFS file servers where the product is installed work normally.

Diagnosis

The issue is caused by a design limitation in the Linux kernel fanotify module. For further information, refer to the kernel bug report at https://bugzilla.kernel.org/show_bug.cgi?id=62221.

Solution

There is no workaround available. However, we recommend that you avoid running on-access scanning when creating new files on CIFS file shares.
