BOE/Webi Error

Question

Dear All,
We are facing production server stability issue. From this Friday in morning almost each 30 min WebIntelligence Service is crash. When users are trying to refresh report it give following error
The Web Intelligence Server could not be reached. Contact your Business Objects administrator. (Error: RWI 00236) (Error: INF)
I check the memory uses by Web Intelligence and it is only 200 MB to 400 MB. I am attaching system configuration file.
When I restart the Webi report server and Webi Job Server we are getting following error.
An internal error occurred while calling the ' initlnstance API' (Error: WIS 30270) (Error INF)
This error only resolves when I restart all the services. This problem repeat on each 30 min in morning. Now there a pattern I have observed in last 2 days. We different data load in morning starting from 6:30 AM to 11:30 AM. After the data load complete we have some schedule reports and matrix refresh. Matrix refresh after all data loads, but report schedule when specific data load is loaded. Most of the time problem is occurred after data load. (I am saying most of the time, not always). If some one have any experience in such issue please let me know.
If we check the Business Objects log this is common error u2013
assert failure: (.\ComPluginMgr.cpp:242). (false : Deprecated code, should be executed).
assert failure u2013 this is common error for JobServer Child / Web Intelligence/ Catch Server
When we check Application log common error is u201CTransport error: Communication failure.u201D This error is starting point of problem. JobServerChild and Web Intelligence report server both give this error.
Now we talk to Business Objects support and still talking. They told us to do following setting change by the book.    
1.     Create a New Web intelligence Report service. (Now we have 3 Web Intelligence Services)
2.     We put the -OUTPROC setting into the WebIntelligence Job server and the Crystal Report Job Server. This actually creates new child for its new request.
3.     we had increased the heap size of the tomcat as
MAX_HEAP_SIZE= 1073741824
In the location BO Installation dir\tomcat\webapps\businessobjects\enterprise115\desktoplaunch\WEB-INF\classes
4.     We also increased the java applet runtime to -Xmx 300.
No luck till now. In fact today system is behaving in different way. Users got same error in 12:30 and 2 PM. Now I donu2019t have to restart system/Services. This problem fixed automatically.
Right now we are installing BOE SP4 and I will disable the entire schedule for tomorrow.
Did any one have anything idea or ever encounter this error.
System Configuration
We are running Business Objects XI R2 SP3
Web Server - "Apache Tomcat 5.0.27"
OS - Windows 2003 Std Edi. SP2
Database - SQL Server 2005 SP1
Browser u2013 Internet Explorer 6

Thanks in advance.

Hi Dinesh,
Also, try the following solution.
By default, the value of the executionTimeout attribute is set to 90 seconds in the Machine.config file. This error occurs when the processing time exceeds 90 seconds.
Solution
To work around this issue, increase the timeout value that is set for the executionTimeout attribute in the Machine.config file.
CAUTION Before making any changes to the machine.config file create a backup copy.
To set the executionTimeout attribute, follow these steps:
1. Open the Machine.config file in Notepad. The Machine.config file is located here:
%SystemRoot%\Microsoft.NET\Framework\%VersionNumber%\CONFIG\
2. In the Machine.config file, locate the httpRuntime element.
3. Increase the value of the executionTimeout attribute to avoid timeout errors.
4. Save the Machine.config file.
5. Restart IIS and the Enterprise XI services.
More Information
For a detailed description of each attribute, see "<httpRuntime> Element" in the .NET Framework documentation at
