Adobe crashing when briefcasing multiple documents (Creating briefcase of multiple documents which is searchable)

Additional information on computer

Version Adobe 11.0.0 Adobe pro

Please advise if I've submitted this incorrectly as first time posting in this forum

All below has been done on Win8.1

Additional information & Already tried troubleshooting:

Tried multiple documents (around 10,000)

Tried multiple groupings of documents of difference size (30, worked. 5000, works occasionally. 10,000 works occasionally)

Previously was brief casing 10,000 without any issues

Documents have varying size (none in this section above 400 pages)

Tried brief casing from both over network share & Local machine

Tried multiple machines

Tried running repair on Adobe

Increase hardware specs on machine to double what already had

Tried different sets of folders and files, no change

Changed sleep settings so not to go to sleep during run time

Checked Event-log, and was unable to find anything to indicate what is the exact cause of this.

Only crashing when using the In Multiple Files tool

Happy to provide any other additional information requested
