[dreamyzhang]

• Node.js Version:6.9
• OS:linux
• Scope (install, code, runtime, meta, other?):
• Module (and version) (if relevant):
• Project Adress: https://github.com/dreamyzhang/nodectp

Question 1:

It would be coredump when run some time. as follows:
node: src/threadpool.c:252: uv__queue_done: Assertion `(((const QUEUE ) (&(req->loop)->active_reqs) == (const QUEUE ) ((QUEUE **) &(((&(req->loop)->active_reqs))[0]))) == 0)' failed.

Question 2:

the same node version 6.9. when installed by nvm will coredump like #485.

for Question2

as example : thosttraderapi.so is static linking SSL and I can not do anything for thosttraderapi.so ， and the node that installed by nvm also static linking SSL. This led to the question coredump. How can I do for solove this question?

[ops@smartwindev linux_api_trade_6.3.6]$ nm thosttraderapi.so | grep SSL | more

I tried to remove the assert, recompile node , and it is excute normally. But why is this so? and what can I do for support all the @node.
