Hi,  
I have issues with memory overload of History log when MQTT connection is lost.

 ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/c/c/cccc5e8ea79ab4bfd1b581f0be092385c7187423.png)  
Where can I check which tags and how many are to be transfered and are waiting in In-memory?  
I need to inspect the amount of memory records, because I suspect that not only my data is waiting for transfer upon reconnection.

I use IgnitionEdge on Opto RIO22.

Thanks for help.

Hi [Joze\_Cvelbar](https://forum.inductiveautomation.com/u/Joze_Cvelbar),

This issue appears to be related to MQTT, as such, I'd recommend reaching out to Cirrus Link for support as they manage the MQTT modules. Here is a link to Cirrus Link's [support page](https://cirrus-link.com/contact-support/).
