Some V8 Fatal error while working with buffers.

[Somebi]

Was working on my own Websocket implementation and after serious load got this error:

Frame is not yet complete, mask is missing.

Fatal error in ../deps/v8/src/heap/incremental-marking.cc, line 488

CHECK(success) failed

@Somebi ... could you provide a simple test case that reliably reproduces the issue?

[domenic]

Can you try next-nightly where buffer is entirely rewritten and V8 is updated? https://iojs.org/download/next-nightly/

[jasnell]

@Somebi ... any updates?

[bradisbell]

I don't have a test case... just a note that this occurred to me when running a simple forever restartall. Node.js v0.12.6 on Ubuntu 14.04 x64. Forever 0.14.2.

$ forever restartall
