In FTP transaction, an unexpected RST arrives


Unexpected RST.


An unknown command is sent after changing to PASV mode. The FTP profile is set to inherit it's parent settings.


The issue seems to reproduce only when the FTP profile inherits it's parent settings: ltm profile ftp /Common/another_ftp_sec_prof { app-service none defaults-from /Common/ftp inherit-parent-profile enabled security enabled } when the "inherit-parent-profile" is disabled, the issue is not happening.
