Hi Mone,
there is no setting from client side and it is only happening for first client

Control message in my log file is

LS_session=Sfc43ef37fa0c0025T2849611&LS_table=0&LS _win_phase=28&LS_op=add&LS_req_phase=254&LS_mode=D ISTINCT&LS_id=mainWireNews&LS_schema=headline%20ti mestamp%20colour%20messageid%20fromdb&LS_selector= %4024hrs&LS_snapshot=true&LS_unique=1& from 127.0.0.1:55865

Now i am able to get 1012 messages after setting <param name="buffer_size">200000</param> in adapter.xml

but still it is showing only 1012 messages.

the reason to set 200000 as length is, we are getting one message/sec from JMS and want to display the history of 48 hours

adapter.xml

<?xml version="1.0"?>
<adapters_conf id="xyz">
<metadata_provider>
<adapter_class>com.xyz.nportal.ls.NewsMetaDataAdap ter</adapter_class>
<param name="buffer_size">200000</param>
</metadata_provider>
<data_provider>
<adapter_class>com.xyz.nportal.ls.NewsDataAdapte r</adapter_class>
</data_provider>
</adapters_conf>
