## Symptoms

- * Running `tcpdump` on all interfaces (i.e., `tcpdump -peni any | grep <IP address> `) with SecureXL in User (UPPAK) mode while under heavy traffic load may cause the system to hang.   
* There is no issue when running `tcpdump -peni any host <IP address>` or running `tcpdump` when there is no traffic.

## Solution

This problem was fixed. The fix is included in:

* [Jumbo Hotfix Accumulator for R82](https://sc1.checkpoint.com/documents/Jumbo_HFA/R82/Default.htm) starting from Take 25
* [Jumbo Hotfix Accumulator for R81.20](https://sc1.checkpoint.com/documents/Jumbo_HFA/R81.20/Default.htm) starting from Take 111
* [Jumbo Hotfix Accumulator for R81.10](https://sc1.checkpoint.com/documents/Jumbo_HFA/R81.10/Default.htm) starting from Take 177

If you choose not to upgrade, as a **workaround** , use the `cpdump -peni any host <IP address>` command.
