## Symptoms

- * SmartView Tracker / SmartLog does not show logs from a Virtual System.

* Output of the "`ls -l $FWDIR/log/fw.log`" command on the VSX Gateway in the context of the Virtual System shows that FireWall log file grows - i.e., Virtual System's logs are saved locally.

* Kernel debug ('`fw ctl debug -v <VSID> -m fw + filter log`') on the VSX Gateway contains the following lines:

  `fw_send_kmsg: log buffer for tsid 0 is full`  
  `
  FW-1: fwloghandle_send_log: fw_send_trap failed`
* Debug of FWD daemon (per [sk86321](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk86321)) on the VSX Gateway contains the following lines:

  `log_add_e__logclient: writes logs to local disk because overflow`  
  `
  log_add_e: waiting for connecting callback (log_connected) to be read`
* The above symptoms also applies to non-VSX gateways

## Cause

FWD log buffer is full. Therefore, FWD daemon is not able to send logs.
