[DATE TIME] ERROR infrastructure.logging.DefaultExceptionLoggerHandlerImpl [qtp-39232058-290]: incident [1c5b56ed-3c2e-4fa1-a1c3-cca3e40f0eaa]: java.lang.IllegalArgumentException: key is null

- The issue started after installing R81.10 Jumbo HFA take 79.

## Cause
The Security Management server searches the DNS host in the _/etc/hosts_ file and receives a null answer when it tries to change the domain name to IP.

## Solution
This problem was fixed. The fix is included in:
- [Jumbo Hotfix Accumulator for R81.20](https://sc1.checkpoint.com/documents/Jumbo_HFA/R81.20/Default.htm) starting from Take 26
- [Jumbo Hotfix Accumulator for R81.10](https://sc1.checkpoint.com/documents/Jumbo_HFA/R81.10/Default.htm) starting from Take 110
- [Jumbo Hotfix Accumulator for R81](https://sc1.checkpoint.com/documents/Jumbo_HFA/R81/Default.htm) starting from Take 87
- [Jumbo Hotfix Accumulator for R80.40](https://sc1.checkpoint.com/documents/Jumbo_HFA/R80.40/Default.htm) starting from Take 198

If you choose not to upgrade, as a **workaround**, you can add the management IP as host with the same name of the DNS server. Run the command in Clish:

add host name ipv4-address
