Low memory symptoms
Help | Content Gateway | Version 7.7.3
Under heavy load, the Linux kernel can run out of RAM. The low memory condition can cause slow performance and a variety of system problems. RAM exhaustion can occur even if the system has plenty of free swap space.
Symptoms of extreme memory exhaustion include the following messages in the system log files (/var/log/messages):
WARNING: errno 105 is ENOBUFS (low on kernel memory), consider a memory upgrade
kernel: eth0: can't fill rx buffer (force 0)!
kernel: recvmsg bug: copied E01BA916 seq E01BAB22
Optionally, you can configure Content Gateway to suspend scanning of traffic when the system enters a low memory state. In Content Gateway Manager go to the Configure > Networking > Connection Management > Low Memory Mode tab. See, Connection Management.
