"Disk full" failure, disk not full

[m5k8]

Hi, fresh problem here: "disk full" message on start. Disk ABSOLUTELY isn't full. "df" says so, I also tried to copy some large file to exclude some other peculiar issue. Disk just isn't full.

Filesystem                Size  Used Avail Use% Mounted on
dev                        16G     0   16G   0% /dev

10.24.1.1:/usr/home/data  3,0T  516G  2,5T  18% /home/data.m5k8.net

Pressing OK to ignore doesn't work, program fails to start - error message and splash screen with version disappears and nothing else happens.

Looks like something wrong with STDOUT.

[m5k8]

Hmm... Everything else works fine, only Double Commander refuses to start, so it's really isolated case.

[alexx2000]

Try to execute DC from console.

After rebooting the system, it stopped complaining. For short time. Now it reports "disk full" failure after some time of inactivity. It stays in background, not touched, and out of the blue after an hour or few hours, or another day, the message reappears. After closing the error message window, main window is completely unresponsive. It must be killed. Now the strange part: when starting it from system menu (Arch Linux, KDE Plasma), it compains right on the start and there's no possibility to start it. When running from console, it starts properly! Tried several times, results are consistent. But it works only for some time, then after some random time it complains again with popup message and becomes dead. Here go console messages, but it's after successful start, so maybe not of any help. Now I'll wait for any console message when error reappears.

I'l add that there is no other visible problem with the system, any other app works properly, and I have many of them. Looks like isolated DC trouble.

I have the same issue: Disk Full error message when I have 38Gb of disk space free, but the application runs fine when run from the Konsole.

Same issue here, latest Manjaro Linux. The problem appears only after some time of inactivity (30 minutes).

[alexx2000]

It should be better with DC 1.1.9.
