Rollback Transaction Table showing large value

Hi,

Currently I ran into the issue where indexserver was not starting. After coming across the following thread:

http://scn.sap.com/message/16382753#16382753

I increased the stack size in global.ini and then could start the indexserver but the content of table Rollback Transaction Table (RTT) is showing count 131135.

select count(*) from sys.m_dev_rollback_transaction_table;

How do I make the count 0 in this table? Just waiting without doing any operations does not help.

Thanks,

Nikhil
