SDI timed out on trunk reconfigure request to signalling process
SDI issued a request to all registered signalling processes informing them that their configuration might have changed. Not all replies were received within the timeout period.
You should check your signalling process configuration, and if you are writing a signalling process check that you correctly send an SL_TRUNK_RECONFIG_CONFIRM in response to SL_TRUNK_RECONFIG_REQUEST.
