I am having very similar truncating going on. Bazsi is working on a fix. However, my logs never paused, maybe for a little bit (5-10seconds) but that is prolly just net traffic jumps. Good luck to Bazsi!!!

Has anyone else experienced syslog-ng occasionally pausing for a few minutes, immediately after logging one or more truncated entries? It usually pauses for anywhere from 1-10 minutes or so, and the process seems to be fine during this time (still bound to the port, doesn't appear to be zombied or using up all the CPU or memory, etc), then it continues after the pause as if nothing happened. The entry immediately after the pause is sometimes truncated also. The lines that are getting truncated appear to always be kernel log entries, more specifically from iptables, so I tried both using klogd as well as a file() source using /proc/kmsg, both with the same results. I saw a thread a few days ago about garbled/truncated entries, and what I got from that thread was to set the log_msg_size() option to something larger than the largest line your expecting. I set mine to 2048, and that still has not solved the problem, so I'm not sure if it's the same issue that has been discussed in the previous thread or something different. Below I've listed a few log entries (gathered from tail -f logfile), and my syslog-ng.conf file is appended below my sig.

If anyone has experienced this or has any other ideas that I may not have tried yet, any info you can provide would be most appreciated.
