We actually just ran into a similar issue, and the underlying cause was that the server resources were overwhelmed.

When we checked the server, CPU and RAM were maxing out, which caused a backlog in the routing service.

In our case, we waited 2 days but the Locked state never resolved itself. Since then we have doubled the server specs.

Looks like you had a few Answers posts this morning that all point to limited resources. 

thank you both for your answers,

yes Jared i do have some posts, this customer has a lot of problems; do you think all these problems are related to the resource issue?

the posts are https://answers.laserfiche.com/questions/158860/Exception-of-type-SystemOutOfMemoryException-was-thrown

and https://answers.laserfiche.com/questions/158863/Loosing-data-in-Forms

We checked using the windows monitoring and it seems to be ok

Jason,

We waited and  the Locked state never resolved itself neither, so we had to reasign the task to another user then reasign it to the right user and this worked.

Jared,

yes other submissions going through, it happens randomly,and the routing engine is up and running? 

I'd suggest opening a support case so we can investigate the issue more closely. 

Did you ever get to the root cause of this issue?  I have one form that keeps getting locked.  I look at monitor - it says it's in process but when I click the link to look at it - I get the locked message.  I reassign the task and them I'm able to open the task.  However it seems that this is a recurring issue so I need to know what I should be looking for.  It only seems to happen with a single form - there are other form processes that are working well.

Please advise.

Thanks

Sandy

For us and some others, it was an issue with insufficient resources on the server.

The best place to start would be monitoring the Forms server to see if, or how often, it maxes out the CPU/RAM and go from there.

How did you unlock them once your CPU was available again?
