test: loosen condition to detect infinite loop

[yosuke-furukawa]

Under heavy load condition, this condition is strict that the test detects infinite loop.
So I have to loosen the condition more. currently I set the recursiveLimit is 100.
if over 100, throw Error that detects infinite loop.

this condition can detect original infinite loop problem and reduce the count of test failure like #1856 (comment)

[silverwind]

Can that condition still be met with that kind of increase? I wonder when v8's Maximum call stack size exceeded triggers.

[yosuke-furukawa]

$ node --v8-options
--stack_size (default size of stack region v8 is allowed to use (in kBytes))
        type: int  default: 984

984 kBytes is enough to call 100 recursive calls. I guess over 10000 loops, we should consider the Maximum call stack size exceeded warnings. (I tried 10000 loops, I cannot see the warnings).

My pull request decides the infinite loop when the recursive counts over 100 but received udp message count is less than 10.

I know this value is not perfect, I should loosen the value from limit + 1 (11) to X. it is not so easy to decide proper X for me.

If someone has suggestion, I will follow.

Well, I wouldn't put too much thought into it. LGTM if it increases CI reliabilty while still catching a real infinte loop.

[Fishrock123]

LGTM, 100 depth recursion is pretty trivial for a test imo.

CI for good measure, if it looks good, land it. https://jenkins-iojs.nodesource.com/view/iojs/job/iojs+any-pr+multi/752/

[yosuke-furukawa]

some tests are failed, but those tests are unrelated to this PR.

[Fishrock123]

Unrelated, yes, but slightly worrying. PR still LGTM to land.

Haven't seen either of these before:

cc @nodejs/crypto, any idea what's up with the last one?

Cant read an error message out of that, but I guess we could update the test certs:

$ openssl x509 -enddate -noout -in test/fixtures/agent.crt
notAfter=Nov 15 09:32:49 2013 GMT

Thank you for your review.

[silverwind]

Have to blame these random ARMv7 errors on the CI again, I can't reproduce this one in 100 runs on my pi2.
