Thingworx Mashup Crash After Open for a Long Period of Time

[JK_10744682]

Hi all,

My team has a mashup that is essentially a dashboard that is kept open in our plants for long periods of time without refresh. Specific details of the mashup aren't important for the issue we are seeing. After being open for longer periods of time, the mashup will crash with this error:

Has anyone encountered this before or know of any way to prevent this from happening? We would like these dashboards to be open during the shifts on monitors in the plant without having to refresh due to a random crash after being open for a while. Any input is greatly appreciated!

Hi @JK_10744682 

Wouldn't an AutoRefresh with a target of 8 hours that would trigger an Expression with TW.location.reload() effectively solve this?

I'm looking at this from the perspective of time invested in finding out the root cause (which is theoretically the correct path) versus just time invested in this option.

Interesting. I would have expected after 8 hours the browser session is expired and you'd have to re-login.

I would guess they are calling services on timer, and Mashup Runtime logs is what leaks memory.

I would check the console logs. The error says Out of memory, so you need to find out what is eating your memory. It might be a widget with memory leak. Developer Tools (F12) can help finding this.

Having an auto-reload might help, I would use a frequency below session-timeout (30min by default).
