            Bug ID: 118605
           Summary: Blocked a few seconds when opening document over CIFS
                    vers=3.0 on Kernel 4.15
           Product: LibreOffice
           Version: 6.0.0.3 release
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: LibreOffice

Description:
Hi,

Our files a mounted via fstab (CIFS) on Ubuntu 16.04 LTS (kernel 4.15) and when
we try to open a document (calc, writer, ...), libreoffice is totally blocked
(before splash screen) for some seconds (~20-30 sec) and after that it open
fine.

It seems that this problem is not present with kernel 4.4.x and if i use
vers=2.0 of CIFS it works with all kernels.

It appears more often when the document is saved with a password.

Don't know where is the problem (kernel or Libo) but if someone can test it. 
I do not have debug logs.. If someone can tell me how i can get some debug
info, just tell me..

Thanks!



Steps to Reproduce:
1. Mount a network folder over CIFS vers=3.0 in fstab. Use kernel 4.15
2. Open a libreoffice document (try with and without a password in document)
3. Try with a older kernel (4.4 by example) or also another Libreoffice
version, 5.4, 5.3

Actual Results:
LibreOffice block for ~20-30 seconds before open

Expected Results:
Have to open quickly without blocking


Reproducible: Always


User Profile Reset: No



Additional Info:
Not sure from which version of LibreOffice it begin. I enter 6.0.5 but i know
is from older version.  

It happens on all our computers.
