[syslog-ng] max-connections(1000)

Hello list, this morning I had some problems with my syslog system I am adding lots of server to send TCP logs to the syslog-ng server. But there are not on the server. After readingon the web, I notice that there is a max-connections parameter on the TCP. So I fix to 50. With this there are more logs, then I added 100 and there more. So I fix it to 1000: source s_all { internal(); unix-stream("/dev/log"); file("/proc/kmsg" log_prefix("kernel: ")); tcp(max-connections(1000)); }; Is this a good idea? How can I check if this is a good maximum connection value? Thanks for all your help and best regards.
