Hey all,
I've see the following in my logs every so often:
kernel: ip_conntrack: table full, dropping packet.
Currently, I have ip_conntrack_max set to 65536 (default, RHEL5).
Keeping memory usage in mind, how much can I safely increase this value? I've got 4GB ram on this box. One of the functions this machine serves is as a static content server, which probably explains the high connections counts, and also means I'd like to keep as much of the OS memory used for caching as possible.
Thanks!
