Bo-Chun Wang has there been failures reported on couchstore, I wonder if both issue this and MB-45320 are related to magma?
Bo-Chun Wang reply
No, the second defect (this one
MB-45322) doesn't happen on magma only. Several performance runs on couchstore failed, too. The runs failed right after backup command was issued. I don't have logs for these runs.http://perf.jenkins.couchbase.com/job/leto/17806/

Sorry, I messed up. Those couchstore runs above are running on 6.6.2 build, and they are using forestdb. They have nothing to do with this issue. Sorry that I made a mistake.
I re-ran the same test on couchstore, and it finished successfully. The couchstore run didn't hit MB-45320 and MB-45322.
Hi Bo-Chun Wang,
Is this a new test, or did it recently start to fail?
Changing component to Couchbase-bucket / storage-engine as issue appears to be with magma.
Given that it appears to be a magma only issue - moving to CC.next
No, it's not a new test. It was working fine until the latest weekly build (4797). Patrick commented in MB-45320 that the issue may be caused by GOCBC-1073. I have kicked off a run with build 4814 having the fix for GOCBC-1073 and will update when I have results.
HI ,
I am seeing a similar issue with backup for the FTS tests.
Some of the tests are as follows :
1. http://perf.jenkins.couchbase.com/view/FTS/job/atlas_collections/461/console
2. http://perf.jenkins.couchbase.com/view/FTS/job/atlas_collections/461/console
First build I observed this : 7.0.0-4726
for this build the backup was failing when run locally also.
For build 7.7.0-4797
I am able to run the test locally with no failure with rebalance. But I am not able to run the same test via Jenkins
I have a good run also with build 7.7.0: 4814

OK thanks Bo-Chun Wang, Jyotsna Nayak - so looks like it was a duplicate of GOCBC-1073.
Bulk closing non-fixed defects. Feel free to reopen if necessary.
The error in the backup log is

I believe the seqno number come directly form the underlying storage engine, so this might be a magma issue. The memcached.log will log slow operations, so it be worth check them, will need server logs for that case too.
