I've started seeing /var/log/messages growing in size indefinitely with these lines:
Aug 1 12:47:27 linux-jblp syslog-ng: POLLERR occurred while idle; fd='16'
Process 1947 is this:
root 1947 1 1 12:45 ? 00:00:03 /sbin/syslog-ng -a /var/lib/dhcp/dev/log -a /var/lib/named/dev/log
/proc/1947/fd doesn't have a file
I have no idea why this started happening or what this means in practice. Any ideas?
