since upgrading from 1.5.1, I regularly get this error:

Assertion failed: (!(handle->flags & (UV_CLOSING | UV_CLOSED))), function uv_close, file ../deps/uv/src/unix/core.c, line 95.

it's the third time today, so there will be more opportunities to debug. I'm checking out master and recompiling with --debug now, so I can give more info if it happens again

I'm doing a lot of spdy development, so it could perhaps have something to do with openssl upgrade - dunno. I've also noticed another error lately too, since the 1.6.1 upgrade it's crashed on socket write after hangup - but I don't know if it's related - perhaps to the writev commit

how can I debug this better?

That looks like a double close or a corrupted libuv handle. Can you check the debug binary's backtrace with gdb or lldb?

sure. I went to master, but it tells me 'let' is a reserved keyword so I went back to tag v1.6.1 and reconfigured with --debug --gdb

I attached gdb to the running process and continued.. is there an easier way of launching iojs without having to do that? without the ability to relaunch iojs, I'm slightly impaired in my ability to do dev... I'll try and work around it for now

You can turn on core dumps (ulimit -c unlimited) and then inspect the core dump in gdb.

There might be some core dumps already there in /cores.

just checked and there aren't any... I hadn't known of that feature until now, actually. so far still no crashes... seems go go wonky when I'm right about the time I'm gonna get a feature done, so here's to getting things done 👍 it'll crash again soon... cheers

ok, it just happened to me again, however there is still nothing inside of /cores. it happened this time when I pressed ctrl-c to close it.. I do remember on sunday it was crashing though. I re-ran ulimit -c unlimited so hopefully it'll give a core dump

EDIT: just added it to my zshrc, so in case I accidentally change terminals again it'll dump.. :)

is this related to b64983d ?

I can do further investigation if necessary

btw, since I've upgraded to 1.6.2, I've not crashed since (but then again, it didn't crash all day the other day either.)

EDIT: if there's a way to truncate the dump, even still, if it helps, I'll still be glad to give it to you (only thing "private" is some self signed certs I made last week). want me to xz and put it on a server?

I see you're using the fsevents module. That module has a couple of known issues (see e.g. fsevents/fsevents#52) that I haven't gotten around to fixing yet. Closing, let's move this to the fsevents issue tracker.
