## Symptoms

- * A syslog server with protocol "TLS over TCP" is configured.

* Logs are not sent to the syslog server.

* The CA certificate for the syslog server was not uploaded.

* Memory consumption by rsyslogd process increases.

## Cause

If the certificate is not uploaded and the syslog server's certificate is not signed by a known CA that exists in */opt/fw1/bin/ca-bundle.crt*, no matching certificate will be found and no logs are sent to the server. As a result, the system repeatedly attempts to establish the connection every time there is an action that triggers the creation of a log.

Because of these repeated connection attempts:

* Logs are not sent, as the connection to the server cannot be established.

* Memory usage increases, as each connection attempt allocates a new certificate file buffer (approximately 1.4Mb).
