Description: In Linux Mint 21.3 I work a lot with network documents (documents on a remote shared location also running linux and accessed through ssh). If I open one network document (calc) and one local document (calc) and run a "save" on the network document, during the save even the local instance hangs. As I work with very large documents, the whole libreoffice local and network instance can hang for more than 1 minute in every save. My question is why the local file also hangs if the upload of the network save is slow. Shouldn't they two instances be independent? I understand the hanging of the remote document but I don't justify the hanging of the local document. Steps to Reproduce: 1. Open a big (> 30MB) network shared document (preferably through ssh) 2. Open a local document 3. Click "Save" on the network shared document 4. Try to use / edit the local document. It's impossible because even the local instance of LO is hanging! Actual Results: Both local and network edited LO instances hang when a save is executed on the remote document. Expected Results: Only the network edited LO instance should hang when a save is executed on the remote document. The local opened document/instance should be fully functional without hanging and without being affected by the network edited instance. Reproducible: Always User Profile Reset: No Additional Info: I'm using the following LO version: Version: 24.2.4.0.0+ (X86_64) / LibreOffice Community Build ID: aa225b41352f22c60f41fb9fa03c23b4e9359266 CPU threads: 8; OS: Linux 5.15; UI render: default; VCL: gtk3 Locale: el-GR (en_US.UTF-8); UI: en-US Calc: threaded
