Ok, so not fixed. Btw there are more leaks in there around eve.json.

Updated by Peter Manev over 4 years ago

Yes.
So in a different angle of the chase of this leak. I simply reverted the search and started Suricata with BP filter that negates ftp and ftp-data

not port ftp or ftp-data

After some runs and back and forts I came up with this leak (it seems non related to the issue here) - wondering if it is connected somehow or it needs its separate issue.
