Reports Server Process gets crashed in 10.1.2.3.0

Question

Hi,
We have 5 standalone production reports servers (10.1.2.3) load balanced through netscalar. We observed that the reports server process gets crashed intermittently which kills the reports jobs in the queue. Error as below is seen in the ipm.log under $ORACLE_HOME/opmn
08/08/12 10:38:21 [4] Process Crashed: rep_brnors05_frs_standalone~ReportsServer~rep_brnors05_frs_standalone~1 (498925945:6108) - Restarting
08/08/12 10:38:27 [4] Starting Process: rep_brnors05_frs_standalone~ReportsServer~rep_brnors05_frs_standalone~1 (498925946:0)
08/08/12 10:38:34 [4] Process Alive: rep_brnors05_frs_standalone~ReportsServer~rep_brnors05_frs_standalone~1 (498925946:2836)
Any idea wat could be causing the problem.. any configuration changes that need to be done like to set or increase some timeout parameters in the rep_server.conf, etc. Each time process crash is for exact 6 secs. It clears the failed jobs queue during this time. Do not see any jobs starting or ending during these 6 seconds.
Reports server version - 10.1.2.3.0
Platform - Windows
Report server type - Standalone
(Affecting our production environment ... Any suggestions, workarounds are highly appreciated)

Michael,
Below is the file change. When we set it to 'true' Viewer performed correctly.

2. Then a new configuration parameter "passNullParameterAsNull" needs to be set in configuration.xml under <viewer section with default value as false and which is an optional one. Usage :
<viewer queryRefreshPeriod="3000" queryRequestTimeout="1000" longRequestRefreshPeriod="6000" longRequestTimeout="10000" userDefinedConnections="true" passNullParameterAsNull="true" logLevel="debug" laf="dc_blaf" pageNavigation="true" switchWorksheetBehavior="prompt" defaultLocale="en" disableBrowserCaching="false" enableAppsSSOConnection="false">
When passNullParameterAsNull="false" , that means, when null is passed as parameter from one sheet to another during drill to link, the value will be converted in between to the value which is set as "ShowNullValueAs" in second sheet. eg: if ShowNullValueAs = "" in second sheet. Null value passed from first sheet will reach as value "" in second sheet. If passNullParameterAsNull="true", then Null value will always be passed as Null to second sheet irrespective of the value of "ShowNullValueAs" in second sheet.
