# sk184722 - SNMP and cpstat Report CPU User Time (cpu_use) as 0 After Long Uptime

| Products | Security Gateway |
| Versions | R82.10, R82, R81.20, R81.10 (EOS) |
| OS | Gaia |

## Symptoms

- * On a Security Gateway, SNMP monitoring and `cpstat` show CPU user?time (`cpu_use`) suddenly dropping to 0%.
* When you run this command on the Security Gateway in Gaia Expert mode:   
  `cat /proc/stat`, you may see the `cpu_use` counter reach the maximum 32?bit unsigned integer value: `cpu_use=4294967295`.   
  After the counter wraps, tools report: `Processor user time = 0`
* This behavior appears after long uptime and may occur sooner on systems with many CPU cores.

## Cause

A component that reports CPU user?time statistics stored the cumulative `cpu_use` counter as a 32?bit unsigned integer.  

After long uptime, the counter reaches its maximum value (4,294,967,295) and wraps, causing the reported CPU user time to appear as 0%.
