I open a remote smb document with libreoffice, do any modification and save the document. The document is only saved in the corresponding .cache/kioexec/krun folder, but is not written back to the remote smb folder. Another symptom is that .cache/kioexec/krun has plenty of temporary folders. Just in case this information is useful: In System Settings->Workplace->Start and Shutdown->Background Services, the Network Watcher and Recent Document Watcher services are Not running.

Wrong duplicate, sorry. As you can see, we have a lot of issues with Samba shares! Please feel free to tackle some of then; perhaps even Bug 397742.
Jaime, does this happen only with LibreOffice, or also with other non-KIO apps like Inkscape and GIMP?
