Replicator in Android get stuck at busy state when it goes back to online from offline

humpback_whale · October 15, 2019, 1:47am

Hello all,
As the title descript, I disconnect my device from the internet and update a value in the couchbase server dashboard. After internet reconnection, I saw the following log :
W/CouchbaseLite/NETWORK: C4Socket.completedReceive() handle -> 4089772456
W/CouchbaseLite/NETWORK: C4Socket.write() handle -> 4089772456
W/CouchbaseLite/NETWORK: completedWrite(long) handle -> 4089772456, byteCount -> 268
V/CouchbaseManager$Abstra: Replicator busy
V/CouchbaseManager$Abstra: Replicator busy
Replicator not turing back to idle. And the updated value not push to my CBL.

I am developing this on Android Studio. I tried this on both CBL 2.5.3 and 2.6.0. They all behave the same.
The replicator is set to push and pull mode, I also set it to continuous mode.

Thank you

It looks like you have network logging enabled but not sync logging. Please enable sync logging.

@jens thank you for your suggestion. I set the logging domain to all and level to debug. Here is the log when it stuck in busy. I read through them, only found that the replicator seems stuck on the last document(3352). But I can’t understand why it is stuck on the last document.

In the first log, the replicator is waiting to receive one revision from the server (Now waiting for 1 'rev' messages; 1 known sequences pending), but it never arrives, at least in the part of the log you’ve shown.

I’m suspicious of the line

W/C4Socket: completedWrite(long) handle -> 4089772456, byteCount -> 263

It’s a warning, so it may indicate a network error, but LiteCore doesn’t get notified of the error. This warning message seems to be in JNI or Java code since I can’t find it in LiteCore itself. @blake.meike, do you know what that warning means?

humpback_whale · October 16, 2019, 12:59am

Does this have anything to do with Sync Gateway? Does any Sync gateway setting have anything to do with reconnection after losing the previous connection?

humpback_whale · October 17, 2019, 10:00pm

@jens For couchbase-lite-android, is there any way that I could change the default heartbeat interval for the WebSocket connection? I think this might be the parameter but there is no documentation on how to config it. Please clarify me if I am wrong. Thank you!

jens · October 22, 2019, 11:55pm

No, there’s no public API to change the WebSocket heartbeat interval. What’s your rationale for needing to change it?

humpback_whale · October 23, 2019, 8:17pm

When the Couchbase lite replicator stuck in busy state, I found that after 5 minutes, with a message “connection reset by pair”, the replicator reconnects sync gateway, and it goes through offline->connecting->idle. And this behavior is what I am expected. I think this is caused by heartbeat timeout. However the waiting time is a little be long for me. I am thinking if it is possible to modify the heartbeat interval to a shorter time so that replicator could react quicker to internet reconnection.

jens · October 24, 2019, 8:03pm

after 5 minutes, with a message “connection reset by pair”, the replicator reconnects

“Connection reset by peer” means that the server disconnected. That probably means Sync Gateway detected it wasn’t getting any traffic from CBL, i.e. it’s SG’s heartbeat, not CBL’s. Have you checked your CBL logs at the time of the disconnect to see what happened?

I’m curious why CBL isn’t sending heartbeat messages, or why SG isn’t receiving them. I see above that I pointed out a possible network error at the Java level that may not be getting through to the core replicator. So it may be that data can’t be sent for some reason but the replicator doesn’t know it.

blake.meike · October 24, 2019, 8:45pm

That message from C4Socket is not really a warning. It simply means that core is informing the java layer that the socket object @4089772456 has succeeded in writing 236 bytes to the wire.

Very little of this log is generated by the java layer. I’m not sure I can add anything. It looks like the replicator is legit busy and that it is awaiting one more byte (progress 3351/3352). No idea what that byte could be…

jens · October 24, 2019, 9:21pm

Something might be wrong on the Sync Gateway side. Looking at the logs again, the last thing that happens is that CBL requests a document from SG, and the request gets written to the socket, but then it never receives any response. So I wonder what’s happening on the server side.

fatmonkey45 · October 24, 2019, 10:24pm

Similar situation is happening, also total documents number on the replicator keeps increasing and completed count remains at 0. Appreciate any clues in resolving this,

@fatmonkey45, you’ll need to turn on more logging. What’s there is just showing byte counts going through the socket, which isn’t useful for diagnosing this kind of thing.

Database.setLevel(DomainLevel.ALL, LogLevel.Verbose) produces no changes in logs

borrrden · October 29, 2019, 3:01am

That method is deprecated and does not function correctly anymore unfortunately. We are trying to make it function in at least a semi-usable way for the next release, but you should use the new logging API indicated in the link.

Got the Verbose logs out. Replaced bytes with …

@humpback_whale : This seems like the same situation as before: CBL is requesting a document revision from the server, but never receives a response.

fatmonkey45 · November 8, 2019, 3:02am

@jens Thanks! So is there any way we can get it sorted? Is there a recommended network configuration for the sync gateway server? Or a recommended network configuration between SG and Couchbase ?

Is there something specific we can look for to determine why no response is received?

benjamin_glatzeder · November 8, 2019, 10:35am

I’d like to chime in that I ran into the same or at least very similar issue.

Setup:

CBL 2.7 SNAPSHOT (from around 2019-10-31)
SG 2.6
nginx as loadbalancer

CBL logs

--- no more logs for several minutes. No sync is happening during this time.

The logs show a few queries at first and then that the document update of the device is not pushed. The CBL status is busy. Continuous pull and push sync starts working again after killing the app and then restarting it. I also observed that the busy state (but no sync) happens frequently when reopening the app after it was in the background. In the app the replication is stopped as soon as the app goes into background and is started again once it goes into foreground.

I checked SG warning and error logs and there were no logs. I also looked into nginx error logs and there also was nothing logged.

Would it help if I provide a minimal Android app which demonstrates this behavior in order to find the root cause?
