## Symptoms

- * The Security Gateway stops processing traffic after policy installation.

* Secure Internal Communication (SIC) is lost between the Security Gateway and the Management Server.

* Check Point commands fail with errors about "`/vs0/dev/fw0`".

  Example 1:

  ```
  
  [Expert@MyGW]# hcp -r all
  ^C/usr/bin/python3: cpdev_user_ioctl: ioctl failed to device /vs0/dev/fw0
  : Unknown error -1
  ```

  Example 2:

  ```
  
  [Expert@MyGW]#cphaprob stat
  Unable to open '/vs0/dev/fw0': Connection refused
  ```

* Linux commands keep working as usual.

* The *$FWDIR/log/fwk.elg* file on the Security Gateway contains this line repeatedly:

  *cpaq_msg_q_enqueue: Wait-queue limit reached*
* Reboot of the Security Gateway solves the issue.

  However, it occurs again after some time.
