[syslog-ng] max-connections

I've got a central logserver on syslog-ng and am getting the following in my logs: syslog-ng[26180]: Error accepting AF_UNIX connection, opened connections: 100, max: 100 but I clearly have source s_tcp { tcp( port(50514) max-connections(1000)); }; source s_udp { udp(); }; in my syslog-ng.conf and the server was restarted since this change (it was made a while ago). Can anybody tell me why this is? Is it possible that it's the udp which is hitting the 100 limit (I thought since udp was connectionless this would unlikely)? -- Hari Sekhon
