Looks like you've shutdowned Scheduler or underlying Executor.

But，how to shutdowned Scheduleror or underlying Executor.

[artem-zinnatullin]

Do you call Scheduler.shutdown() somewhere?

I haven't call, but I just upgraded version。
Now is
compile 'com.squareup.retrofit2:retrofit:2.0.2' compile 'com.squareup.okhttp3:logging-interceptor:3.0.1' compile 'com.squareup.retrofit2:converter-gson:2.0.2' compile 'com.squareup.retrofit2:adapter-rxjava:2.0.2' compile 'io.reactivex:rxandroid:1.2.0' compile 'io.reactivex:rxjava:1.1.5'

Please help me, my god
Thanks！

In addition to upgrade version, didn't do anything

[artem-zinnatullin]

ok, can you please try:

1. Keep RxJava version at 1.1.5 and downgrade RxAndroid to 1.1.0 and try
   reproduce the issue.
2. Keep RxAndroid at 1.2.0 and downgrade RxJava to 1.1.3.

[akarnokd]

Do you have something like this?

source
.subscribeOn(Schedulers.newThread())
.observeOn(AndroidSchedulers.mainThread())
.subscribe().unsubscribe()

Something seems to unsubscribe the NewThreadWorker the same time subscribeOn tries to request.

Dear，Here is my Demo.
https://github.com/lzt1226/AlexIntentDemo/tree/master/app/src/main/java/com/alex/alexintentdemo/http
I think ，As a result of RxAndroid version is too low, and Retrofit2.0.2 don't match
In our official launch of the APP, the incidence of the bug is probably more than one over one thousand

[akarnokd]

I've run your demo in emulator, clicked on the buttons but no exceptions were thrown. I also tried with recent versions:

    compile ('io.reactivex:rxandroid:1.2.0') {
        exclude group: 'io.reactivex', module: 'rxjava'
    }
    compile 'io.reactivex:rxjava:1.1.5'

It is a probability bug，There were 1000 + time in our bug list

[akarnokd]

I can't reproduce it. Maybe your demo app is too simple to demonstrate it, or you are missing reproduction steps.

Either way, try with Schedulers.io() instead of Schedulers.newThread() as the former is not shut down when the operator finishes using it.

[Jaikant]

I just saw a similar stack trace uploaded to crashlytics. Could it be proguard related?
The versions of some of the prominent components are:

    compile 'com.squareup.retrofit2:retrofit:2.0.0'
    compile 'com.squareup.retrofit2:adapter-rxjava:2.0.0'
    compile 'io.reactivex:rxandroid:1.1.0'
    compile 'io.reactivex:rxjava:1.1.0'

I haven't called a scheduler shutdown or unsubscribe (immediately after subscribe)
Not sure how to reproduce it. The stack trace is below.

@Jaikant Great!
Yeal, I also am such version。
When I use the latest version, no problem。

Did you solve that @lzt1226 ?
