yaml specs log files are empty

[Joan]

Hi,

We are currently using Bamboo 6.9.2.
We have already used Java Specs without troubles.
But now we are trying to use new Yaml Specs v2.
The issue is that the log files generated from the Yaml Specs Scan are empty:

# ll -a

All log files have 0 bytes, of course there is no problems of disk space (582 gigs available) neither of permissions, as you can see files are created but empty. Other log files are generated properly.

We have no idea what's going on? Should log file content be enabled someway?

Thank you,

Joan.
