recv fails with buf == null about node-unix-dgram HOT 3 CLOSED

I think it's because of a missing error check. Can you try this patch?

   var rinfo = {
     size: buf.length,
     address: {},

I'd be curious to know what error you get because I can't really think of plausible recvmsg failures (except, maybe, EAGAIN.) On what platform is this?

I can try, but the problem is that I can't reproduce it, it happened just once yesterday but the code has been running for months and curently there are no more errors like that.

This issue has been open for over 4 years with no progress so I'm going to go ahead and close it.
