Ido Kanner commented on ASTERISK-22278:
---------------------------------------

Nop, I meant that different processes that are not Asterisk, were able to write to a folder that Asterisk (and only Asterisk) was unable to do so.
Hence, something is wrong with Asterisk.

There is no SELinux, or AppArmor activated.
The disk has no error.
When the directory owner is the asterisk user, and using "su - asterisk", I'm able to read, write and delete file, same as root.
Yet when I execute Asterisk as the Asterisk user, or as the Root user it fails.

Other PBX works on the same directory, with the same code base of what I wrote.
I'm able to duplicate it on a new machine.

So hence, there is a problem somewhere in Asterisk. Either in some settings that I can't figure out, or in the code base of Asterisk that make it work different then other IO operations from different processes.
