I have recently installed netdata on my Debian 8 server (monitoring software) and afetr installing my Debian 8 server is reporting the below two alerts constantly.
- 1m ipv4 tcp listen overflows = 37 overflows
- 1m ipv4 tcp listen drops = 3 drops
I was wondering if anyone could suggest any settings to reduce/stop these errors, maybe some sysctl.conf settings will correct this?
Currenty I have attempted to reduce with the below sysctl.conf settings (with no luck).
net.netfilter.nf_conntrack_max = 524288
net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_max_syn_backlog = 65535
net.ipv4.tcp_max_orphans = 65535
net.ipv4.tcp_synack_retries = 3
net.ipv4.tcp_max_tw_buckets = 1440000
net.ipv4.tcp_tw_recycle = 1
net.ipv4.tcp_tw_reuse = 1
net.core.somaxconn = 65535
net.core.netdev_max_backlog = 65536
