RE: BUG #17192: The csvlog is corrupted

I found out the problem was that 2 db instances were logging to the same file.
The file seems not to be locked when 1 system is logging so they were conflicting and combining lines.
So this is not a bug.
Sorry for the inconvenience.

Description:

The content of the csvlog file seems to be corrupted. Most lines are correct but some lines seems to be merged.
I'll put 3 lines here, first and third lines are correct, but the second line is corrupted. This result ofcourse in errors when I try to import the logs into a table via the copy command:
