"The Server has been restarted. Please reload the page"

Hello @ikarisg 

When did the upgrade happen?

Is the issue happening every time?

Have you restarted the application and verified it?

Any trace details?

Hi @ikarisg were you able to find a solution? Thank you!

No we haven’t found a solution. We have rebooted the server multiple times, and we’re still getting this issue on a random occasion. Makes our work a little bit more harder.

Hi,

I’m seeing this error for the first time and is also related to an upgrade to 2022.  I have a few theories I’m testing out to try and resolve.  Specifically I think it’s due to an error being thrown by a customisation possibly related to Newtonsoft.  This is very much a theory at this stage. 

Do you have any customisations that use Newtonsoft in your instance?

Any solution for this yet my customer is on Acumatica Cloud ERP 2023 R1
Build 23.106.0050 + and we are getting the same error ?

Hi,

Spent some time looking to solve my particular “Server Has Restarted Problem” yesterday.  Raised a separate topic on how to replicate my particular example

My case appears to be due to a customization that used to work in R2021 but no longer does in R2022.

We get this error all the time, in addition to “The session has expired, please reload the page”.  We have an on-premise install and I do feel that possibly this error started happening with an upgrade but it has been going on for awhile so I can’t say that for sure.  We have minimal customizations so I do not think this is related to a customization.  Has anyone on this thread found the solution?

The default recycling settings for an IIS AppPool is to recycle every 29 hours. If this is not adjusted, it will cause issues.

We recently observed this error when code was written within FieldUpdated that in turn called .Update() on the same DAC as shown below for SOOrder (note the offending last line):

        protected void _(Events.FieldUpdated<SOOrder.customerLocationID> e, PXFieldUpdated del)
        {
            del?.Invoke(e.Cache, e.Args);

            if (e.Row == null)
                return;

            SOOrder row = e.Row as SOOrder;
            if (row.OrderType != Constants.OrderTypes.SI)
                return;

            row.CustomerRefNbr = "INVENTORY";
            row = e.Cache.Update(row) as SOOrder;
        }

What gets called later after FieldUpdated?  RowUpdated.

If the custom “SI” OrderType above is not used very often, or 

if another graph in the system has code similar to this 

and its page is used very little, the error would arise intermittently.

Any solutions for this? I have a client using Acumatica Cloud ERP 2025 R1
Build 25.101.0153.5+ and we're experiencing the same error.

This might be due to two reason, there might be any package for published or someone restarted the application. Please review the apply updates (SM203510) screen to check any publish or update happened.

This can be due to several reasons. Customization Published, someone has restarted the site or site in maintenance mode.

It is 100% linked to IIS restarting every 29 hours by default.  There are several steps you can follow that set your IIS to restart every night at a certain time and the problem will go away!
