I added some additional tracing - it never returns from
osi_StopListener.... Haven't gotten any further in than that.
Woops, that was wrong StopListener below... It's obviously spinning in
this code:
void osi_StopListener(void)
{
extern int (*sys_killp)();
extern int rxk_ListenerPid;
while (rxk_ListenerPid) {
(void) (*sys_killp)(rxk_ListenerPid, 9);
afs_osi_Sleep(&rxk_ListenerPid);
}
sock_release(rx_socket);
rx_socket = NULL;
}
