Are the messages generated on one host and sent across the network to a logging host? If so, you are experiencing the poor syslog design. Syslog entries are sent across the network via UDP and UDP does not guarantee reliable delivery. Some other services like NFS also use UDP but have application level recovery for dropped UDP datagrams. But syslog just lets them get lost. This would tend to happen when the network is busy.
If the messages are generated and logged on the same host, then they should not get lost.
