Hi, In my method for processing MWI information I do the following: void *messageBuffer = mwi_info.rdata->msg_info.msg->body->data; Today I received a crash report detailing an EXC_BAD_ACCESS caused by “attempting to dereference garbage pointer”. What could have potentially caused this? If I can’t do anything to stop it then what can I do to handle it?

Afaik body is NULL when the MWI subscription is running out. So you need to check and handle that case before accessing ...body->data. Sebastian.
