Hi, this morning I noticed that since the 31st (and the update to 8.2.1 from 8.1.0) my backups keep failing with the same error message: Too many empty directories. Run "find /home/yellowtent/boxdata/mail -type d -empty" to investigate In the log this can be found for such a task: 2025-01-03T07:15:34.868Z box:shell backupformat/rsync: find /home/yellowtent/boxdata/mail -type d -empty 2025-01-03T07:15:41.125Z box:shell backupformat/rsync: find /home/yellowtent/boxdata/mail -type d -empty errored BoxError: find exited with code null signal SIGKILL at ChildProcess.<anonymous> (/home/yellowtent/box/src/shell.js:72:23) at ChildProcess.emit (node:events:519:28) at maybeClose (node:internal/child_process:1105:16) at Socket.<anonymous> (node:internal/child_process:457:11) at Socket.emit (node:events:519:28) at Pipe.<anonymous> (node:net:339:12) { reason: 'Shell Error', details: {}, stdout: '/home/yellowtent/boxdata/mail/solr\n' + [..] '/home/yellowtent/boxdata'... 2599152 more characters, stdoutLineCount: 20073, stderr: '', stderrLineCount: 0, code: null, signal: 'SIGKILL' } 2025-01-03T07:15:41.205Z box:backupupload upload completed. error: BoxError: Too many empty directories.

As far as I can see the server should not be running out of resources during this and no related error seems to be in dmesg.

yes, that sounds good to me. For the moment I have increased the limit on my server by simply adding another zero.

@robi those directories were legit directories under user data and not created by some plugin . I think only @jagan can answer how so many directories can be created. Maybe they are synced from some external source.
