[SR-Users] [dispatcher] freeing already freed pointer, called from core: core/xavp.c: xavp_free

[Henning Westerholt]

Hello Denys,

good to know that you found a way how to solve this. You can create an issue on our github tracker about it, it should not produce this error. Please add your cfg examples and also dispatcher.list examples as well to reproduce it.

Cheers,

Henning

I have fixed this issue moving AUTORUN from [htable:mod-init] to [core:worker-one-init].

event_route[core:worker-one-init] {
        route(AUTORUN);
}

Hello!

The configuration below leads to a CRITICAL message in the console.
Please let me know how to avoid this issue.

event_route[htable:mod-init] {
  route(AUTORUN);
...
}

route[AUTORUN]  {
  if ( ds_select("9", "4") ) {
    xlog("L_WARN", "[$cfg(route)] *ds_select* $xavp(_dsdst_[0]=>uri) $xavp(_dsdst_[1]=>uri) $xavp(_dsdst_[2]=>uri)\n");
  }
...
}
