Web managment interface drops connection after 36hrs or so

Hi everyone,

 

 

just wondering if anyone else has run into this issue or not. Due to our BIGIPs crashing randomly (due to what we now appears to be a possible memory leak issue) we decided to leave a web session to the unit's active, displaying the performance stats, specifically ram usage. The PC running the session to the two units displays on a central 52" LCD monitor so everyone in support can see the status.

 

 

What is happening is that after 36hrs or so the connection to one of the unit is lost. If I attempt a refresh it just states that an internal error occured and to check the logs. If I close the browser and reconnect it is fine.

 

 

I've looked at the logs on the offending unit and in the webui.log I found this

Going by the date/time of this error, this occured when I tried to refresh the page.

 

 

Now this does not happen on the 2nd BigIP unit so it seems odd the first unit is doing this. The 1st unit is in standby mode.

 

 

Has anyone else had this happen?

 

 

We are running the latest 9.4 build of the firmare on both units.
