I can't help more with configuring and using app_java, because I am
not using it. Maybe Konstantin can lead further.<br>
<br>
If you get a core dump, then you can send the backtrace taken with
gdb to see where the crash happened.<br>
<br>
It is no longer the previous crash, which was a buffer overflow.<br>
<br>

style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Sorry,
did not see that it was actual a fix to the crash. Anyway,
guess I’m having all sorts of issues with the app_java
module. If the –Djava.class.path is not the first
parameter, the classpath does not appear to be set. After
switching to just one parameter, the “child_init” function
appears to be called with all sorts of ranks and then
Kamailio crashes. My java code just logs it (using log4j)
and returns 1. Also, the log4j log only showed the -127
being called.<o:p></o:p></span></p>
