SUMMARY: How many connection can I have to a tcp() source? 10? Why?
I have been experiencing a problem with a syslog-ng (1.4.11) server
seemingly only allowing 10 connections to a tcp() source. A quick tour of
the code found the offending code at line 341 in afinet.c:
self->super.max_connections = 10;
Elsewhere in the file I see this (with code missing):
if (c->num_connections >= c->max_connections) {
#FAIL TO CONNECT
}else{
#SUCCESSFULLY CONNECT
}
Unless this is not the code to handle tcp() sources, I think I've found
what I need to change in order to fix this. My question is to Balazs, or
anyone else with insight into the design of this daemon: Why is the limit
set to 10? I want to change it, potentially to something very high (100
sounds about right for now), what impact is this going to have?
