## Symptoms

- * On a Security Gateway that is **not** in the VSX mode, Dynamic Balancing stays in the `Initializing` state.

* Resetting Dynamic Balancing with the `dynamic_split -r` command does not resolve the issue.

* The `$FWDIR/log/dsd.elg` debug file contains this error:

  `
  Failed reading active instances num`  
  `
  read_array: strtol failed for cmd: (fw ctl multik stat | grep Yes | awk '{print $5}' | sort -u -n)`  
  `
  read_array: failed to convert X-Y
  `
* The `/var/log/messages` file does not contain logs related to the issue.

## Cause

CoreXL affinity (CoreXL affinity determines which CPU cores handle specific firewall instances) is misconfigured. Multiple CoreXL Firewall instances were assigned overlapping CPU core ranges instead of maintaining a one-to-one mapping between instances and CPU cores.

Example Misconfiguration:

* CoreXL Firewall Instance 1: 2-5
* CoreXL Firewall instance 2: 4-7

In this example, cores 4--5 are assigned to both CoreXL Firewall Instance 1 and CoreXL Firewall Instance 2.
