This occures when maximum simultenous connection from your machine exceeds.. so apparently your ip_conntrack table is full, you can review your table
with:

# cat /proc/net/ip_conntrack

The max number of connections is set in

# cat /proc/sys/net/ipv4/ip_conntrack_max

You can increase it with:

# echo "some_number" > /proc/sys/net/ipv4/ip_conntrack_max

But be sure to use not much high value as it will use more RAM.

for 64 mb ram nearly 7000 connection is allowed

by my experience u shoud upgrade the  128 mb ram (16000 connection)

to avoid packet loss

Hi there, i have the same issue, was wondering what would be the right amount of connections on a box with 1.5 gig dual channel ddr?

as prasadeapen has mentioned .. u can set roughly 7000 connections for 64mb ram machine.. so u can set it accordingly
