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.
