Memcached error #134: Temporary failure
Hi all,
Ive been testing Couchbase server Version: 1.8.0 enterprise edition (build-55).
I got 2 couchbase buckets, and one memcache bucket.
I'm able to backup both couchabase bucket, but not able to restore both.
When i want to restore bucket2 with cbrestore that it fails on error #134.
Error on key '159779': Memcached error #134: Temporary failure
Command i use :
/opt/couchbase/bin/cbrestore -a /couchbase/backups/testbackup2012051600/bucket2/*
And bucket 'default' i am able to backup, and restore.
Am i doing something wrong or, ?
With kind regards,
Siebren
Bucket size : 100 MByte
Bucket Items : 156436
Item Size : i have no idea.
The couchbase server is running on Ubuntu 12.04 LTS
There is a known issue that down near 100MByte, sometimes you'll run out of metadata and constantly get a temp fail reply. I've been able to work around this myself by going up to 150 or 200MByte. Can you try the same?
The errors are gone when i increased the bucket size from 100 MB to 150 MB. But is is strange, that only 25% (25.6 MB) is in use for meta-data.
After a few minutes putting data into both buckets, there errors were there again. And like before, on the 'bucket2' bucket the errors appeared again. But on the default bucket, there are no errors.
There are some known issues with memory accounting in some releases. It's likely due to this. There is a hotfix which support has for release 1.8.0 that should be available in a future release as well.
A temporary failure should not occur during a restore. That seems like an issue in the restore.
Can you give me an idea of how big your bucket is, how many items you have, and the average item size? Also, which platform is this on?
