 Thanks for replay! It point me to right way. 
My problem was in that really in some session shellcode was split in two packets (i made this mix of session some years ago, and forgot how i do it), and target port does not present in stream preprocessor.

Maybe it was bug in snort 2.9.1, because it reassemble session, without declaration port in stream preprocessor.
