purging event objects using partition_utils

Hi,

We have a partitoned event_t table and we intend to purge the old event data but on doing so we received

Command - partition_utils -o purge -s 02042014 -e 04042014

Output - No action is required due to non-existence of purge event(s).

However, there are events with their associated items having status=4 (closed) present which fall between the start and end dates of the above command.

But the same are not getting purged and throw the above output message.

Please advise on how to use this command for purging partitons
