[Tipc-discussion] Re: Latest panic

The dropped messages are rather confusing. They seem to have destination address <1.1.13>, but have somehow ended up on <1.1.19> according to the dump. Maybe this is ok, since they are multicast messages, but only if they were carried as broadcast messages over the network. I think the correct destination address should be <1.1.0> if that is the case, but I haven't studied the implementation well enough to know how it works here. It is also obvious that net_route_named_msg() in net.c should allow a second lookup even of multicast messages, not only of named messages as it does now, so this is a bug that must be corrected (I will fix it). But I can not see any relation to the crash here. Did anything happen to node <1.1.17>, or is the lost/re-established link a result of the dropped messages ? /Jon Mark Haverkamp wrote: >I ran my 4 node test yesterday with a lock around access to the >quarantine_head in buf_safe_discard.
