## Symptoms

- * The following error messages found in /var/log/messages file:  


  `
  [DATE TIME] fw-1 kernel: [fw4_0];fwldbcast_flush_ex: fwlddist_buf_ldbcast_unread is not being reset fast enough (ur=3942,fwlddist_buflen=3ee4)`  
  `
  [DATE TIME] fw-1 kernel: [fw4_0];fwlddist_adjust_buf: record too big for sync. update SET for table 269 failed. fwlddist_state=1a`

* Pdpd process stops working and create a core file.
* The pdp_super_sessions kernel table hold entries with more than one kbuf, for example:  

  ```
  [Expert@fw-1:0]# fw tab -t pdp_super_sessions -u
  localhost:
  -------- pdp_super_sessions --------
  dynamic, id 269, num ents 39, load factor 0.0, attributes: keep, sync,

  ```

* "pdp monitor all" does not always shows all sessions.

## Cause

If machine authentication fails, the entry in pdp_super_session grows larger and larger until it causes pdpd process to crash.
