We have Linux Server running few VMs, Apache, Application Server, My SQL
Now it showing: "sysctl grep conntrack" command
ip_conntrack: table full, dropping packet
printk: 18 messages suppressed
(those 2 lines over and over but once 24 messages than 13, than 4 with no end in the counsel)
All computers and devices at times are getting conflict IP, at times will not get an IP from our Cisco Firewall/Server. But if I phisicly I disconnect the server from the switch, restart the Cisco than all is well.
Before this happens the network was working on and off for a wile until today it will not budge (IP saturation). Few months ago the Apache was restarted and the Application Server was resolving fine, all was well. Between 100-150 IPs were successful dedicated throughout the network. Our table does support over 1024 IPs. It looked like keeps increasing little by little over time.
Our head office is not allowing us to restart the Linux Server, Since rebuilding the database will take months of work.. (so no restart)..
Please, anyone can suggest of commands or ideas I can try to resolve this issue?
