Nginx waiting connections growing (1 reply)

Hi All,

Active connections: 551
server accepts handled requests
69542 69542 79078
Reading: 0 Writing: 2 Waiting: 524

After I have moved my server from 32 bit Ubuntu 11.04 to Ubuntu 64bit 12.04 and I am observing they is sudden rise in the Waiting and Active connections and these values are growing daily and not comming back? it is a problem?

KeepAlive timeout : 65
Nginx : 1.6.2

On previous 32 bit Ubuntu 11.04 machine the values were pretty low and all of sudden I am seeing rise in the metrics any help appricated.

Regards
KV
