# sk102737 - RouteD daemon might consume CPU at very high level on ClusterXL member running Gaia OS, when there are issues with cluster sync interfaces

## Symptoms

- * Output of '`top`' command on ClusterXL member shows that '`routed`' daemon consumes CPU at very high level (which might cause fail-over).

* */var/log/messages* file on problematic on ClusterXL member repeatedly shows:

  * `routed[`*PID* `]: cpcl_instance_manager_listen_accept(`*N*`): task_accept failed, errno = 24`
  * `routed[`*PID* `]: cpcl_instance_manager_listen_accept(`*N*`): peer_alloc failed, errno = 0`
* */var/log/routed.log* file on problematic on ClusterXL member under trace ('`Global - Cluster`') repeatedly shows:

  ```
  
  cpcl_slave_restart(N): Entering...
  slave: quiting peer (id = 1).
  peer_remove(N): Entering !!!!
  peer_remove(N): resetting sockets
  cpcl_slave_quit(N): closing peer socket 25
  slave: closing slave sock (id = 25).
  cpcl_clear_recv_queue(N): entering
  entering cpcl_slave_init()
  cpcl_slave_init(N): instance 0 connection waiting for select to return 
  cpcl_slave_restart(N): Exiting...
  cpcl_slave_connect_complete(N): entering
  cpcl_slave_connected_to_master(N): entering
  cprd: state switching from 1 to 1
  cpcl_slave_connect_complete(N): exiting
  ```

## Cause

In some scenarios, if there are issues with cluster synchronization interfaces (e.g., when 2 physical Sync interfaces are defined, which is against [sk92804](http://supportcontent.checkpoint.com/solutions?id=sk92804)), RouteD might not be able to accept a connection from peer cluster member. Due to a socket not being closed, eventually RouteD reaches the limit of open files for a process.
