 Description   

We are currently in testing MariadbColumnStore as suggested and have reached a deadend while trying to insert test data with below error :

"CAL0000: VBBM::getBlocks(): version buffer overflow. Increase VersionBufferFileSize. Overflow occured in aged blocks. Requested NumBlocks:VbOid:vbFBO:lastFBO = 1:0:2253300:2253399 lbid locked is 4088832"

While trying to solve the problem as mentioned in KB Article we performed below mentioned steps.

Steps : 1

1) No Active Transaction as we stopped all jobs.
2) Stopped Mariadb
3) Increased VersionBufferFileSize in ColumnStore.XML
4) Start Mariadb

Step : 2

1) Stopped Mariadb
2) Renamed VersionBufferFileSize
3) Start Mariadb

After performing above steps we still facing same issue with DML and DDL Statement.

It would be extremely useful if you could include the DDL/DML causing the problem, as well as a support report which is obtained by running "columnstoreSupportReport -a". This will create a directory "columnstoreSupportReport" in your current dir. Tar that up and include.

If your MariaDB and ColumnStore is idle with no active transactions or any activity, shouldn't the "versionbuffer.cdf" be zero or very small. It is still showing with 1GB !!
