Couchbase server 5.5.3 - Where can we change the XDCR Max Replications

Hi,
There is an article mention about Max Replications:
https://developer.couchbase.com/documentation/server/3.x/admin/Misc/Trbl-beam-smp-issue.html

May I know where can we can change in couchbase server 5.5.3 ?

Thank you

Regards,

Hi tinygipxy,

This setting has been deprecated since 4.x.
I saw your other post regarding beam.smp’s high memory consumption and would like to suggest restarting the nodes. (refer Beam.smp memory usage) .
If this doesn’t fix your issue, please provide logs and I will follow up.

Thanks!

Hi Pavithra,

That post only mention about upgrade version and my version already 5.5.3. Let me explain my issue in detail:

  1. The beam.smp process is steady increase memory usage and after about 4 hours, it will take up full memory of machine and then couchbase server is shutdown.

  2. This is my machine memory&CPU usage:

As you can see there are 4 time couchbase server shutdown at 3PM, 8PM, 1AM and 7AM

  1. This is the memory usage history of only beam.smp

  1. For all couchbase log, you can download from here:

Hi,

I’m runnig couchbase 6.0.0.0 and experienced System OOM where the VM is not responsive on redhat 7.6. Here is a log snippets. The beam.smp process is consumming the memory to the point where the VM has to be restart.

I see a mentioned the XDCR Max Replication is deprecated in 3.x but from the couchbase-client there is parameter xdcr-replicate option for --settings.
