speech 0.32.0 causing memory leak

1. Specify the API google-cloud-speech 0.32.0

2. OS type and version Ubuntu and CentOS

3. Python version 2.7.3

4. Step to reproduce I have a chatbot program where it let user speaks to the computer and computer will response back. The program will call speech to text module from time to time. I notice that after few minutes, the program crash with OSError: [Errno 12] Cannot allocate memory. I ran the program again along side top command and I notice that the memory usage is gradually increasing. After several debugging process, I found out that the problem came from the google-cloud-speech usage. I downgrade the library to the one that I used before (0.29.0) and run the program again. I notice that this time, the memory usage is not that high and it didn’t increase over time.

top output when I’m running the program with google-cloud-speech 0.32.0

top output when I’m running the program with google-cloud-speech 0.29.0

Here’s the code that I used for this test. memory_leak_test.txt

@crwilcox I have yet to updated my grpcio but updating google-cloud-speech to 0.33.0 seems to fix the issue as well

@akmalhakimi1991, this should be resolved as we believe the root of the issue was fixed in a recent update to grpcio. If you update grpcio by running pip install grpcio --upgrade your issue should be resolved. This will get version 1.11.0 which has the fix.
