Hello,
have you set modparams for tm module related to reparsing the invite
or on dns failover?
The build_local() should be used only in some specific cases and want
to be sure it doesn't get executed somehow when it shouldn't be.
Cheers,
Daniel

Local messages are malformed in Kamailio 4.4.X.
For example after
receiving an error response (603) to an INVITE message, the ACK is
generated with header Max-Forwards concatenated to header CSeq and
double CRLF, which is wrong.

The fix for that seems to be just the order of append_str in function
build_local() from tm\t_msgbuilder.c.
append_str( p, method, method_len );
+append_str( p, CRLF, CRLF_LEN );
append_str( p, MAXFWD_HEADER, MAXFWD_HEADER_LEN );
-append_str( p, CRLF, CRLF_LEN );
