Concurrent connections in UTM 9.312

Hi,

after updating to the newest UTM Version 9.312-6, we noticed a constante rise of "concurrent connections", which stopped all our traffic last night, when the concurrent connections went up to 256000 and a "nf_conntrack: table full, dropping packet" message in the kernel.
Has anyone experienced the same problem or has an idea how to solve this?

Frank

Do all of you have IPv6 enabled? Does anyone experience this problem without having IPv6 enabled?
