It appears I am getting an OverlappingFileLockException on line 80 in the 
org.geoserver.platform.resource.FileLockProvider class


               while (currLock == null && count < maxLockAttempts) {
                    // the file output stream can also fail to be acquired due 
to the
                    // other nodes deleting the file
                    currFos = new FileOutputStream(file);
                    try {
                        currLock = currFos.getChannel().lock();
                    } catch (OverlappingFileLockException | IOException e) {
                        IOUtils.closeQuietly(currFos);
                        try {
                            Thread.sleep(20);
                        } catch (InterruptedException ie) {
                            // ok, moving on
                        }
                    } // this one is also thrown with a message "avoided fs 
deadlock"

                    count++;
                }

The file that is locked is the filelock/#####.lock file in the data directory.  
Do you know what may be causing this?

Hello

I have using GeoServer 2.24.4 on Windows with Java 11.  When I make a WMS 
getCapabilities request for a workspace that only contains postgis layers it 
eventually times out.  I would like to note we are having no issues on linux, 
this only seems to be a windows problem and I have no issues making a WFS or 
WCS getCapabilities call.  I have also tried disabling URL checks and enabling 
URL checks to allow all strings, but neither have made a difference.


I attached the full error but here is a snippet
