Hi Ricta,

 

 Checking our  database, it is possible your switch encountered some sort of corruption. Try running the following commands from shell as root:

 

root@uer02:RE:0% nand-mediack -C

root@uer02:RE:0% nand-mediack
Media check on da0 on ex platforms 

More info: https://kb.juniper.net/InfoCenter/index?page=content&id=KB20570&cat=SRX_240&actp=LIST

 

Also check for any Core Dumps under "show system core-dumps".

 

If there are core dumps or problem persists after running Nand commands, you may consider opening a TAC case to discard any software or hardware issues.

 

Regards,

 

If this clears your concerns please mark as Solved!

Hello,

 

try do perform a recovery installation on your device, EX4550 is very susceptible to internal flash errors due to written syslog messages:

Hello, 

 

If rebooting the device fixes the issue, it might be a file system issue, as mentioned other colleagues on this thread, try doing a format install and see if that resolves the issue.

 

I'm wondering how often this happen.. 

 

Thanks
