Low disk space - Less than 50 MiB is left on the system directory partition

I'm seeing the following message in WebStorm suddenly.

"Low disk space - Less than 50 MiB is left on the system directory partition ('/dev/disk1s1')"

I'm not familiar with that partition and I'm not sure it's something I need to do something about.

Is this something WebStorm will resolve itself or do I need to clean up some directories?


I'm not sure that it's related to WebStorm. when does the issue occur? what is a result of running run df -h in the system terminal?


I also got this error right now on windows 11

Less than 50 MiB is left on the system directory partition ('')

all my drives have 100gb+ free

Hi, Wangxinli Thanks for the log. I have checked the code logic of the disk space check three times, and it I think our code checks the disk space correctly.

In the log, I can see that you have about 30 Gib free disks near the 2023 09-26 13:37.

But the IDE noticed your disk space only has about 33Mib remained in the below timestamp:

2023-09-19 02:48:44,352 [403013057] WARN - #c.i.o.a.Application - Low disk space: 33533952
2023-09-26 03:42:55,676 [45111420] WARN - #c.i.o.a.Application - Low disk space: 33488896

Do you use the IDEA near the 2-3 PM and check the free disk space at that time?

It is possible that the disk space is indeed not enough during that time. For example, an updater or some other tools use a lot of disk space, so the IDEA detects that low disk at that time and reports it.

Can you please refer to here https://superuser.com/a/750414 to enable the windows' free disk checker and set the Sample Interval to about 10-15 seconds. So when you see the IDEA reports it and you could check the window reporter there to see if your C disk has enough space near the report time?

You can also change the “File | Settings | Appearance & Behavior | Notifications | Low memory detected”'s Popup type to “No popup” to disable the check.
