Bug #4479
Updated by Davide Pesavento about 6 years ago
I am trying to transfer a reasonably sized file (10MB) over Ethernet unicast using putchunks and catchunks. The segment size for putchunks is 8800, MTU on the interface is 9000. Configurations are same as #4012-10. I find nfd receives a SIGSEGV but not because the host is out of memory. Please find the GDB backtrace below and attached. ``` #0 0x00007ffff4f68342 in std::_Rb_tree_increment(std::_Rb_tree_node_base const*) () from /lib64/libstdc++.so.6 #1 0x0000000000474029 in
