System memory usage will increase over time without boundaries.
The rsyslog daemon will retry, and memory will continue to increase. This could potentially exhaust system memory.
Remote-syslog servers configured with TCP protocol that cannot establish a connection (or has a unreliable connectivity).
Fix the connection, remove the invalid or flaky servers from config, OR use the UDP protocol.
The new syntax used for rsyslogd remote-servers forwarding configuration requires specifying for each forwarding action a linked list queue type. This will implicitly use the default queue size of 1000 messages (or lower for earlier versions of rsyslogd).
