I have also had the following error on UCLA recently:<br class="">
<br class="">
1504524817.021009 FATAL: [NFD] std::bad_alloc<br class="">
<br class="">
<br class="">
I’m also investigating other nodes that have restarted in the last couple of<br class="">
days.<br class="">
<br class="">
I am about to install a scheme for running the nodes in the Testbed in DEBUG<br class="">
and when nfd<br class="">
restarts, capture the current set of nfd.log files. I have nfd.log being<br class="">
rotated and am only saving<br class="">
the last 10 copies of 10MB each. So, they can disappear fairly quickly with<br class="">
DEBUG turned on.<br class="">
But with my scheme I should be able to save copies of anything FATAL that<br class="">
happened recently.<br class="">
I’ll also be collecting ‘nfdc face list’ info so we can know what faces were<br class="">
pointing where when<br class="">
something FATAL happened.<br class="">
<br class="">
I’m open to other suggestions.<br class="">

Dear folks<br class="">
<br class="">
ARIZONA node is not working at the moment. `nfdc status` gives error:<br class="">
error while connecting to the forwarder (No buffer space available)<br class="">
<br class="">
The error went away when I restart NFD. However, I wonder what does this<br class="">
error message mean? I've never seen it.<br class="">
Neither system memory nor disk space was full, and there wasn't high CPU<br class="">
usage.<br class="">
<br class="">
Yours, Junxiao<br class="">
