## Symptoms

- * Maestro Security Group Member enters a boot loop after you install one of these Jumbo Hotfix Accumulator Takes and reboot:

  * R82 Jumbo Hotfix Take 12
  * R82 Jumbo Hotfix Take 10
  * R81.20 Jumbo Hotfix Take 98
  * R81.20 Jumbo Hotfix Take 96
  * R81.20 Jumbo Hotfix Take 92
  * R81.20 Jumbo Hotfix Take 90
  * R81.20 Jumbo Hotfix Take 89
  * R81.10 Jumbo Hotfix Take 172
  * R81.10 Jumbo Hotfix Take 171
  * R81.10 Jumbo Hotfix Take 170
* Maestro Security Group Member enters a boot loop after you upgrade to the R82 version and reboot.

## Cause

The Maestro Security Group Member crashes and reboots when the Gaia gClish command "`show smo security-group site-amount`" returns the value "`1`".

**Note:** Most Maestro setups have this value set to "`2`", even in Single-Site setups. In these cases, the upgrade is safe.

## Solution

This problem was fixed. The fix is included starting from:

* [Check Point R82.10](https://support.checkpoint.com/results/sk/sk183506)
* [Jumbo Hotfix Accumulator for R82](https://sc1.checkpoint.com/documents/Jumbo_HFA/R82/Default.htm) - from Take 14
* [Jumbo Hotfix Accumulator for R81.20](https://sc1.checkpoint.com/documents/Jumbo_HFA/R81.20/Default.htm) - from Take 99
* [Jumbo Hotfix Accumulator for R81.10](https://sc1.checkpoint.com/documents/Jumbo_HFA/R81.10/Default.htm) - from Take 173

**Immediate Workaround:**

Apply this solution **only** if the Gaia gClish command "`show smo security-group site-amount`" returns the value "`1`". Using this workaround when the returned value is not "`1`" may cause system instability.

1. Connect to the command line on the Maestro Security Group.

2. Configure the value "`1`" for the kernel parameter "`fwha_maestro_single_site`" on all Security Group Members:

   * If your shell is Gaia gClish, run:

     1. `update_conf_file fwkern.conf fwha_maestro_single_site=1`

     2. `cat /var/opt/fw.boot/modules/fwkern.conf`

   * If your shell is the Expert mode, run:

     1. `g_update_conf_file fwkern.conf fwha_maestro_single_site=1`

     2. `g_cat /var/opt/fw.boot/modules/fwkern.conf`

3. Start the installation of the Jumbo Hotfix Accumulator / the upgrade to the R82 version again.
