INVALID_SESSION_ID: Invalid Session ID found in SessionHeader: Illegal Session.

I was uploading the data of OpportunityLineItemSchedule through data loader. The .csv file is having 1,41,000 records. After 21000 were uploaded through data loader I got the error "INVALID_SESSION_ID: Invalid Session ID found in SessionHeader: Illegal Session. Session not found" error. Does anyone have any thought on this?

 

Thanks inadvance.

 

Thanks

Please check 

is the "lock sessions to originating IP" setting turned on in the org ?

 

for this you should nevugate like this

  1. Click Your Name | Setup | Security Controls | Session Settings.
  2. Customize the session security settings.

Go to Session Settings in Setup and uncheck "Lock sessions to originating IP". This fixed the issue for me. Thanks Sandeep above for the insight.
