Case
During backup of your HANA database you get the following error:
[447] backup could not be completed, [1000002] Allocation failed ;
$size$=536870912; $name$=ChannelUtils::copy; $type$=pool;
$inuse_count$=0; $allocated_size$=0
This an error about memory allocation limit for HANA releases newer than SP5. The main result is that statisticserver may fail.
Additionally you see many errors like:
statisticsserver_<hostname>.3<instance_id>05.rtedump.<timestamp>.<pid>.oom.trc
Solution
1- In the HANA Studio navigation, open the “Administration”-tab of the affected system.
2- In the “Configuration”-view expand the statisticsserver.ini and [] memorymanager.
3- Right-click on “allocationlimit” and choose “change”.
4- Set the value to 10% or even higher, depending on the memory capabilities of your host.
5- Go to the “Landscape”-tab and select “reconfigure service” for the statisticsserver service
6- Repeat the backup.
