I've googled this topic and read the mailing list and haven't had much luck improving my situation. I have a very high volume syslog-ng server. I currently have logs that are being received across the network but not being written to disk. This could be as much as 25% of the logs being dropped. The STAT to syslog always says 0 drops. It's a Netro 1405 w/ two CPUs and 1 gig of memory connected to a SAN. syslog-ng is always at 49% CPU and never goes beyond that. What settings can I use to stop dropping logs? This is an output of iostate with an interval of 1. This will give you an idea of performance. As you can see there are no disk waits. Thanks. device r/s w/s Mr/s Mw/s wait actv svc_t %w %b md89 2.0 86.0 0.0 0.4 0.0 0.2 1.9 0 5 md89 0.0 3.0 0.0 0.0 0.0 0.0 0.9 0 0 md89 0.0 1.0 0.0 0.0 0.0 0.0 2.5 0 0 md89 0.0 1.0 0.0 0.0 0.0 0.0 1.2 0 0 md89 0.0 2.0 0.0 0.0 0.0 0.0 1.2 0 0 md89 0.0 61.0 0.0 0.3 0.0 0.1 1.3 0 3 md89 0.0 1.0 0.0 0.0 0.0 0.0 1.5 0 0 md89 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0 0 md89 0.0 2.0 0.0 0.0 0.0 0.0 0.9 0 0 md89 0.0 2.0 0.0 0.0 0.0 0.0 0.7 0 0 md89 0.0 83.0 0.0 0.4 0.0 0.2 2.2 0 3 md89 2.0 4.0 0.0 0.0 0.0 0.0 3.0 0 2 md89 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0 0 md89 0.0 1.0 0.0 0.0 0.0 0.0 0.8 0 0 md89 0.0 1.0 0.0 0.0 0.0 0.0 0.8 0 0 md89 1.0 86.0 0.0 0.4 0.0 0.1 1.2 0 4 md89 0.0 2.0 0.0 0.0 0.0 0.0 0.9 0 0 md89 0.0 5.0 0.0 0.0 0.0 0.0 0.9 0 0 md89 0.0 1.0 0.0 0.0 0.0 0.0 1.0 0 0 md89 0.0 2.0 0.0 0.0 0.0 0.0 0.8 0 0 md89 2.0 751.9 0.0 5.6 0.0 6.5 8.6 0 25
