Not able to delete the HANA XS Instance from HCP trial vertion

Hi

I am not able to open HANA Web based development workbench from HCP free trial edition.

So I tried to reset my account and tried to delete the HANA XS Instance from HCP trial vertion.

Getting the below error while deleting the XS instance -

Message Strip Warning

Unable to delete 'dev': Internal Server Error (500) - Unexpected exception in deleteSchema() called with account 's0004125148trial', and schema 'dev'. Root cause is: unregister of DeveloperUsers from DB instance 'JN4' failed with [129]: transaction rolled back by an internal error: exception 1000002: Allocation failed ; $size$=1048576; $name$=QueryCompilation; $type$=pool; $inuse_count$=30; $allocated_size$=60256; $alignment$=16

Thanks
