## Symptoms

- * Security Gateway / Cluster Member runs out of kernel memory and may stop processing traffic.

* The `/var/log/messages` file shows these messages:

  `kernel: [fw<X_X>];fwconn_record_conn: double record of connection - conn_key ...`  
  `
  kernel: Call Trace`  
  `
  kernel: <function name>`  
  `
  kernel: <function name>`  
  `
  ...
  `

## Cause

During the double record of a connection, the memory that was already allocated for connection handlers, is not released. This leads to a memory exhaustion.
