Constand InDesign Crashing in a Mixed Server Environment and Undeletable Lock File

Question

Hello All,
I have been running into a lot of problems with InDesign recently. I have been working on a 14 MB .indd file with approximately 50 MB of linked files with it. ID will crash with other files open, so it doesn't seem to be file specific. Here are some details about our operating environment:
All files are located on a server running Mavericks with Server 3.0
I am using ID CC 2014 on Windows 7
2 other people are using OSX Mavericks and using ID CC 2014
I will typically have this file open for hours at a time, making occasional changes and updates. Every once in a while I get a windows dialog message that says "The network connection was lost for the file "\\FILEPATH HERE", or the file was modified by another process."
I have checked with my colleagues and they are nowhere near this directory and yet this error occurs.
After I click OK on this box, a crash box occurs for InDesign saying that I must close it. The error details are as follows:

These errors occur at random intervals, and sometimes when links are updated in AI or PS. Is there a connection there?
In addition to this, I can no longer reopen the file, as the crash causes the ID lock file to remain there, giving no access to the .indd file. I cannot delete this file unless the administrator of the server deletes the file.
Does anyone have any insights into these problems? Thank you in advance.

Answer 1

Set up a new group called "Workers" or something like that and put in the Users into that group. Now go to Server.app and assign the Group to your share ADDITIONALLY (not by changing the group you see in the Posix permissions) by hit the "+" sign. Give READ & WRITE to the group. The go to Server > Hardware > Storage and propagate the permissons to the included files & folders.
That should clear you problems by setting up and additional read & write permission by ACL, which is not overwritten, when a user saves a document to "The Box".
