Reason:
The error usually comes if the thresholds set for Number of actions per postback increases.

Solution:
Open SharePoint 2010 Central Administration. Go to General Application Setting and then click on Configure InfoPath Forms Services from InfoPath forms Services section as shown in the figure below:

Here we need to change 2 things.

1- From the Configure InfoPath Forms Services page go to Thresholds section and Change the value set for Number of actions per postback: to max of 250 or 300 as per your requirement. By default it was set to 200.

2- Then go to User Sessions and Change value set for Maximum size of user session data: to a maximum value according to your requirement. The default value set was to 4096 kilobytes.
