## Symptoms

- * The Security Gateway becomes unresponsive after some days. To regain a stable Security Gateway, it is necessary to reboot the Gateway.

* */var/log/messages* shows:

  * snmpd: queryHWSensorData: Could not retrieve data from the config database
  * kernel: nuvoton GPIO: I/O address 0x002e already in use
  * unable to read from nuvoton_gpio driver module

  <br />

* The command ``ls -l /proc/`pidof confd`/fd`` results in this output:


  `o lr-x------. 1 admin root 64 Mar 24 19:35 537 -> /sys/devices/virtual/misc/gpio-nuvoton/input`

## Cause

Each time there is a call for `/sys/devices/virtual/misc/gpio-nuvoton/input`, it is not released, and eventually `confd` reaches the limits of the file descriptor and is blocked from calling a different command.

<br />
