[BUG] Cosmos SDK Netty ByteBuf leak #9023

Closed allenhumphreys closed 4 years ago

allenhumphreys commented 4 years ago

Describe the bug There is a leak in the Cosmos SDK when using the DIRECT connection mode.

The problem seems to only become obvious when services are under continuous medium load. We've had Cosmos deployed for many months and this hasn't been an issue, but shortly after going live and having sustained traffic increase above a certain level, all our services started running out of heap memory and experiencing OutOfMemory exceptions.

A leak this bad is highly concerning. Fortunately we were able to switch our service to use GATEWAY mode to bypass the issue.

We went through several mitigation steps, including:

All to have it become abundantly clear that the leak was coming from the Cosmos SDK, and that there was nothing we could do.

We subsequently enabled ADVANCED Netty leak detection to get a record of the last code to access the ByteBuf. That log showed that the last access is a call to release() at RntbdResponse.java:198. That code has suspicious comments, but more importantly it helped me confirm that attempting to switch to GATEWAY connection mode would likely bypass the leaking behavior, which it did.

@allenhumphreys thanks for reporting this and putting out a great summary of the issue. We are working on this and plan to have a fix out there by the end of this week.

timwhit commented 4 years ago

Thanks, @kushagraThapar. Will there be a new release with this fix as well?

kushagraThapar commented 4 years ago

@timwhit yes, there will be.

kushagraThapar commented 4 years ago

This PR has fixed this issue: https://github.com/Azure/azure-sdk-for-java/pull/9211

New version will be released this week.

kushagraThapar commented 4 years ago

@allenhumphreys @timwhit - The fix for this has been released - v3.7.1 Please verify.

allenhumphreys commented 4 years ago

It will take some time to test this since we’ve switched over to gateway mode.

kushagraThapar commented 4 years ago

@allenhumphreys - Sure, please close this issue whenever you feel, or if you want, I can close it now, and you can re-open it if you see the issue again. However you want it.

kushagraThapar commented 4 years ago

Closing this, @allenhumphreys please reopen if you see the issue again.

allenhumphreys commented 4 years ago

@kushagraThapar I've updated my services and re-enabled DIRECT mode in my staging environment. I have observed what seems to be new behavior possibly related to this fix. I am receiving io.netty.util.IllegalReferenceCountException and the exception is being logged from RxGatewayStoreModel. Should I open a new ticket? I'm hesitant to enable this in production and I'd really like to because GATEWAY mode is not covered under the Cosmos SLA.

kushagraThapar commented 4 years ago

@allenhumphreys Yes, let's open a new ticket, so we can track it separately. Please paste the complete stack trace in addition to operation details and other important details that can help us. Meanwhile, continue using GATEWAY mode while we fix this.

timwhit commented 4 years ago

@kushagraThapar we were explicitly told yesterday by Azure Operations to NOT use Gateway mode as it has no SLA and there are no guarantees about it's uptime. This is an extremely serious issue and I'll be escalating the new ticket as soon as @allenhumphreys creates it.

kushagraThapar commented 4 years ago

@timwhit - as soon as @allenhumphreys creates the new ticket, we will start working on it. We are taking these fixes with high priority.

kushagraThapar commented 4 years ago

@timwhit - Regarding running on GATEWAY mode, I understand that it advised to NOT use GATEWAY mode, but the reason the mode still is in place is for situations like these. So it is perfectly okay to run on GATEWAY mode, until the DIRECT mode is completely fixed. Also, @allenhumphreys - Based on what you have mentioned so far (RxGatewayStoreModel) looks like you might be hitting the issue on HTTP layer, which might point to a memory leak issue in Http pipeline in reactor-netty. That bug is definitely not related to the recent fix we did, because the fix only touches Direct TCP protocol stack. That being said, I think you can even use DIRECT mode in your staging environment and keep and eye on memory and performance. Since in DIRECT mode (default is TCP) so HTTP's role is not a lot, which should not affect memory that much. Once you create the ticket, things will be more clear and I will be able to provide better recommendation.
