[syslog-ng]How to lessen/fix dropped messages?

[Josh Endries]

Hey all,

We log 20ish hosts to a central log server (many are through stunnel) 
and recently I started getting dropped messages. I see anywhere from 
1-10 dropped per STATS line. This probably has something to do with us 
installing iplog on some machines and increasing the traffic (only 
timely coincidence I can think of) I'm wondering what, if anything, can 
be done to help the situation.

I've read that you can increase the log_fifo_size to help with this 
problem, but I'm not sure what the default value is or what I should set 
it to. Is there a guideline for what to set this for X number of 
machines, or for a certain amount of traffic?

Thanks!
