TMM cores via assert during EPSV command from clients when The FTP filter rewrites the commands.
Traffic disrupted while tmm restarts.
This rarely encountered issue occurs with the use of line feed (NL) characters in rewritten commands.
Use a TCP collect iRule to detect and insert the missing CR.
FTP filter now accepts NL-only line-ending when rewriting EPSV command.
