Could not expand chunk pool for ipnat node

[noobieee7]

Hi,

I have a 1841, running some NATs. I am getting this error. Any idea why is this so? Any how do I go about resolving it?

It means " not enough processor memory left to expand this chunk pool. " ( ie memory is not being released, eventually resulting in chunk memory allocation (MALLOC) failures ). Better you reload the device.

Hi,

Can you share output as: 

show proc mem sort

show ip nat statistic

and NAT configuration.
