InfoPath Error: This session has exceeded the amount of allowable resources + Event ID 5737

Microsoft Office InfoPath is a software application for designing, distributing, filling and submitting electronic forms containing structured data. InfoPath Forms Services uses session state to store the large amount of transient data generated while filling out a form. As a result, front-end Web servers can remain stateless between round trips, and each post back is not burdened with carrying large amounts of session state information over narrow bandwidth pipes.

One of the users opened a ticket with our team By mentioning that he is getting some error message while opening InfoPath forms:

Error Message: InfoPath Error: This session has exceeded the amount of allowable resources

It was a actually a new issue for me so i had started my troubleshooting by debugging the InfoPath forms.

Checked InfoPath form settings, tried to designed a new form, analyzed SharePoint logs as well as Event viewer. While analyzing the event viewer error messages, i found something which was very useful towards the case resolution. (Please refer the below mentioned trace)

Event Viewer details:

Event Type:      Error

Event Source:    Office SharePoint Server

Event Category:  Forms Services Runtime

Event ID:        5737

Description:    

Number of form actions 208, has exceeded 200, the maximum allowable value

Per request. This value is configurable and can be changed by the administrator.

Microsoft Note: In order for the session state database to be properly maintained, the SQL Agent must be turned on for the instance of Microsoft SQL Server where session data is stored. If the SQL Agent is not turned on, expired sessions are not automatically expunged from the session table and may eventually pose a storage problem.

As per the data from the event viewer, it states that we need to check something within central administration as "This value is configurable and can be changed by the administrator". When i checked the Central Administration settings then i found what i was looking for :-)

Resolution:

Increase the form actions in configuring InfoPath services section as mentioned below:-

• Go to Central Administration of the SharePoint server.
• Click on Application Management
• In the section "InfoPath Forms Services"-->select Configure InfoPath Forms Services.
• In the Number of Actions per Post back, enter some max value around 250 or 300 depends on your project form requirement.
• There are chances that the error may retain same even after we increase the number of actions per post back. The second thing we have to increase is the value of "Maximum size of form session state" to 8192. By default it is 4092, by increasing it to 8192 the error should go away. 

If you have any queries/questions regarding the above mentioned information then please let me know...

I would be more than HAPPY to HELP You as well as RESOLVES Your Issues, Thanks
