Hello Johannes,
I've encountered another bug in ibr-dtn. I've been sending multiple 150K-sized bundles from node 224 to node 232 via node 227 with dtnsend, when dtnd on the receiving side crashed. This behavior repeats after dtnd restart. I think the problem is somewhere in dtn client <-> dtn daemon socket communication.
IBR-DTN version: 0.10.0 (build a5297f1)
Please, see dtnd.log and dbg.txt in attachments.
Best regards, Sergey Sireskin

Dear Johannes,
After dtnd works some time under noticeable load, it hangs after pressing CTL+C.

Hallo Sergey,
thank you again for the report. This seems to be a race condition in the socket state machine. Unfortunately, I do not have enough details to understand the reasons for this. Please, can you repeat your experiment with extended debugging "dtnd <...> -d 99" on and send me the log files? That would help me to track down the issue.
Thanks, Johannes
