Can not allocate space (error 95) for file ... using native Linux API, more slower methods will be used [OFileClassic]

See original GitHub issue

OrientDB Version: 3.0.2+

Java Version: 1.8.0_181-b13

OS: Ubuntu 18.10 (x64), Raspbian Strech (9.4) (on Raspberry Pi 3)

Expected behavior

No warnings when using the DB.

Actual behavior

2018-07-24 16:07:48:520 WARNI Can not allocate space (error 95) for file .../orientdb-3.0.4/databases/testDB/appsettingsdata_15_188.pcl using native Linux API, more slower methods will be used [OFileClassic]
2018-07-24 16:07:49:308 WARNI Can not allocate space (error 95) for file .../orientdb-3.0.4/databases/testDB/appsettingsdata_159.cpm using native Linux API, more slower methods will be used [OFileClassic]

(some parts of the path above have been omitted with ...)

I keep getting a lot of these warnings on two different Linux OS-es (though both Debian based) since 3.0.2 (in all versions up to including 3.0.4) and I’m wandering is this really a problem/performance hit? No such warnings in 3.0.1.

Steps to reproduce

Just run the DB (non-embedded via server.sh) and write data to it. I’m using spring-data-orientdb in my app to access/use the DB but I don’t think that’s the reason for the warnings.

We’re experiencing the same issue in 3.0.13. OrientDb Server doesn’t want to start.
