Hi all.
I have an application running in weglodic server with oracle 10g enterprise edition database.
When ever i perform a particular task in a particular page , iam getting an error " No more data to read from socket".
This error is not occuring when i do the same from the backend procedure instead of java calling the procedure.

when i googled "No more data to read from socket" , it says that the db session java makes is getting stale or useless.

This db procedure uses a big object with numberous collection objects inside. When i comment out a particular piece of code ( 15 to 20 lines) where a particular collection object is getting populated , this error is not occuring.

could anybody tell me the diagnosis , this is actaully urgent and its only in production , and develpoment and QA environments are running fine.

Have a look in the Alert log, and in the trace files.

You can get this message as a result of an Ora-3113 or an ORA-7445

Thank you sir.
You are right.
I found in the trace files the following lines.

ksedmp: internal or fatal error
ORA-07445: exception encountered: core dump [memcpy()+116] [SIGSEGV] [Address not mapped to object] [0xC40635015A000088] [] []

I have reported this to oracle.
It would be more helpful if we could get some more details of this error, so that we could start analyzing the cause.
Thanks.
