It started after i put in File Crawling Configuration :
Excluded Paths For Crawling: .\thumb.db
.\Thumb.db
.\thumbs.db
.\Thumbs.db
Excluded Paths For Indexing:
.\thumb.db
.\Thumb.db
.\thumbs.db
.\Thumbs.db

I didnt identify any \Thumb.db in this txt file that could cause this error. It is happenig with a lot of txt, pdf, xls files.

Try to replace \ with /.

that worked.
Should I do that with all the excluded paths?

.*/thumb.db
.*/Thumb.db
.*/thumbs.db
.*/Thumbs.db
.*\.class
.*\.css
.*\.ini
.*\.exe
.*\.dll
.*\.pyd
.*\.js
.*\.lnk
.*\.xry
.*\.iso
.*\.download
.*\.json
