Thu 14 Jan 2010 03:43:47 PM UTC, comment #8: I think the cause rather might be 'conn->pcb.tcp = NULL;' in err_tcp(), because the one in netconn_delete() is executed after do_delconn() (which in turn executes netconn_drain()).

Tue 12 Jan 2010 03:32:18 PM UTC, comment #1: Thanks for the excellent report! I don't know where I had my mind when writing that code, but setting recvmbox/acceptmbox to SYS_MBOX_NULL from the application thread is of course wrong and the source of this bug. |
