Well you are right, with the last version of snort 18.104.22.168 i did disable the flow preprocessor, i did compile the 22.214.171.124 that will also support stream4udp packets so it does work with both stream5 and stream4 configuration (but will not work together, you must select if you want to use stram4 or stream5 option)
With the both versions (126.96.36.199 & 188.8.131.52) i still have a problem after some time (could be hours and could be minutes) snort exit with this message:
" (snort), uid 0: exited on signal 11 (core dumped)" I havent got any clue what could cause it and looking into web (google and such) didnt resolved much information...
I am curious if it is just me that get this error or some of you do get it as well, if someone have got any clue how to debug it and see what cause this fault i could have a bit more progress, but as for now i am kinda stuck with lack of information.
I did try snort with almost all the working methods but again i do get the message and snort stop doing what it should be doing (blocking
