Open Bucket Slow Or Timesout from Local but not on Production

.NET SDK
1

Hi,

I am connecting an Azure hosted Couch Base server on Couchbase Server Community Edition 7.0.2 build 6703.

The code that I’m running is using CouchBaseNetClient 2.7.27.

We used CastleWindsor to create an instance of the ClusterHelper at application start. The code then calls a method to get the users cache everytime a page is loaded.

IBucket bucket = ClusterHelper.GetBucket(“default”);

The above method “GetBucket” is taking over a minute locally and then timing out. A second load will usually load instantly. This doesn’t happen in the production environment. As you can imagine this is making debugging locally very painful and I’m wondering if there is a reason why it is taking over a minute to GetBucket?

Thanks

First, I’d point out that SDK 2.x is no longer supported and isn’t receiving updates. I’d recommend moving to 3.x as soon as possible.

The most likely cause for your problem is initial bootstrapping. SDK 2.x doesn’t bootstrap the connections until the first call to GetBucket, so this is when it’s initially making connections, negotiating auth, etc. The most likely cause for bootstrapping issues like you describe would be networking related, either not all ports are open that should be or host names/ips are not resolving correctly when connecting remotely.

You may try turning on debug level logging to get more information.

Thanks for the info. I’ve used the Getting Started with the .NET SDK section and setup a little console app to test with. I get the same behaviour when connecting to the ClusterAsync.

Is there some logging I can turn on in Couchbase as the current logs look bare.

The answer to the logging question, unfortunately, is “it depends”. The instructions are somewhat different in SDK 2.x .NET 4, SDK 2.x .NET Core, and SDK 3.x.

It sounds like you might be trying SDK 3.x now, so the trick there is to just add a ILoggerFactory to the ClusterOptions from the standard Microsoft.Extensions.Logging infrastructure. If you use Couchbase.Extensions.DependencyInjection this is done automatically, but you’ll need to configure logging on the DI container.

Here’s a bit of a down-and-dirty example you can use for a quick test command line app: couchbase-net-client/ClusterFixture.cs at master · couchbase/couchbase-net-client · GitHub

Hi again,

I’m not sure logging in the application is going to tell me much. The problem is the code doesn’t get to bucket because the ConnectAsync times out. Sometimes when it gets through it works instantly and I can get the bucket.

var cluster = await Cluster.ConnectAsync(
// Update these credentials for your Local Couchbase instance!
“http://server”, “login”, “pass”);

await cluster.WaitUntilReadyAsync(new TimeSpan(0, 5, 0));

var bucket = await cluster.BucketAsync(“default”);

@jon.bick

The instructions I sent above link the application logging infrastructure into the Couchbase SDK so that you receive SDK logs as well. Setting it to the Debug log level will get you lots of details.

Hoping there is some useful information in there. The operation has timed out or was cancelled errors don’t tell me anything.

9

Ahh, try using “couchbase://” instead of “http://” in your connection string, “http://” is old school.

10

Sadly its producing the same errors.

11

Interesting, If i take the port number off the end of the connection string it attempts to poll alot and then complain about DNS and attempts to access on port 11210.

12

Modern couchbase should bootstrap on port 11210 using GCCCP (or pre-6.5 CCCP), or on port 11207 if using TLS for encryption. HTTP bootstrap on port 8091 is the old method which is less efficient. Can you get me the updated logs now that you’re using “couchbase://”? Note: If using TLS it should be “couchbases://”

13

So this is without specifying a port number.

There might be some useful diagnostics in the error messages or logging. See the doc for information on logging.

It sounds like you don’t have an SRV record for your local server in you DNS (which is normal).

16

Yes, the error for DNS SRV is normal, it’s just a warning in case you are trying to use DNS SRV to bootstrap instead of giving a list of nodes manually.

That said, I think it may be causing your problem. It’s not 100% clear from the logs, but I wonder if the DNS SRV query is timing out rather than just erroring quickly due to some design factor on the DNS servers. Try setting “EnableDnsSrvResolution” to false on your options object and let’s see what that does.

If that doesn’t work, can you send a copy of your complete bootstrap code?

17

The DNS indicated - 194.168.4.100:53 - does exactly that.

% time curl 194.168.4.100:53
curl: (7) Failed to connect to 194.168.4.100 port 53: Operation timed out
curl 194.168.4.100:53 0.00s user 0.01s system 0% cpu 1:16.39 total

18

Interesting, so I set EnableDnsSrvResolution to false and it’s working instantly when going direct to a node. However I am still seeing the issue when going to the server. Logs to follow.

19

I think I need to rehost Couchbase on the updated port?
