how to monitor changes in a table when there is huge amount od data

[tbdyzm]

Hi,
I used Changes(Table) to init changes, and there are nearly 150,000 records in a table, I just changed one record.I used setStartPointNow() and setEndPointNow() to monitor the changes. when I tried to find what changed in the table, changes.getChangeList() went into an endless loop.
Is there a performance bottleneck about the amount of records in a table.
