SUMMARY A few weeks ago, I noticed that randomly, albeit quite regularly, programs will be unable to write to /tmp causing program instability, with a "Disk quota exceeded" error. I found out that the culprit appears to be Dolphin. COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME dolphin 20879 troplo 50u REG 0,47 123506688 2430 /tmp/#2430 (deleted) dolphin 20879 troplo 64u REG 0,47 19574120448 2431 /tmp/#2431 (deleted) dolphin 20879 troplo 67u REG 0,47 92631040 2432 /tmp/#2432 (deleted) tmpfs 24G 19G 4.7G 80% /tmp Despite the partition only being 80% full, programs still can't write anything. Closing all Dolphin windows immediately releases the locked files and restores /tmp writing. STEPS TO REPRODUCE 1. I'm not entirely sure specifically what causes this yet, if I do find the cause I'll let you know, I do use network shares and the embedded terminal extensively, however, it still occurs even when not moving/copying large files from/to the network share. Posting this to see if anyone has the same bug, or any insight. 2. 3. OBSERVED RESULT Dolphin fills up the /tmp folder with temporary files, and doesn't release the held lock after deleting them, causing them to not actually be deleted. EXPECTED RESULT Dolphin should release the lock.

Alright I had unlimited scrollback enabled, and because I use the embedded terminal in Dolphin, that's why it appeared as a Dolphin issue. I set a limit and it doesn't seem to be happening anymore, was the scrollback system changed? I've had it set to unlimited for years and haven't had this issue before, but I remember that it was never actually unlimited, so I'm not sure whether this would be considered a bug or not, as it probably is actually unlimited now.
Thanks for the bug report. In order for this to be actionable, we need to be able to reproduce the bug. Can you provide more specific steps to trigger this?
Hopefully it has the same cause as this one: https://bugs.kde.org/show_bug.cgi?id=508402 So a fix can solve both. I always use the unlimited scrollback, but to the normal terminal. I pretty much never use the one embedded in Dolphin. But to make a test for this bug report, I did it by going to the /tmp folder itself and then opening the embedded terminal and running a few ls and cd commands, but I could not reproduce it, like I could with the aforementioned bug report with just clicking on the modified column to sort it. The unlimited scrollback seems to have been already set, maybe it followed my general Konsole preference (default profile). So I don't know, maybe it needs more testing with more commands.
This does look like the same problem as bug 508402. I'm going to merge this report in with that one. If the bug still happens on your system after that one is marked fixed, please reopen this report. Thanks! *** This bug has been marked as a duplicate of bug 508402 ***
