Wowza Server hanging issue

Hello, We are using latest wowza engine manager. We have average of 1000 users connected to our streams concurrently. We were good with older version. Now we have upgraded & the issue we are facing is that Incoming & outgoing connections increasing from 100,1000,10000,40000...& when it reach 100000 the wowza get stucked. We don't have that much traffic but it shows incorrect connections. We are using Wms panel token security to secure our streams and Wms panel showing correct connections like 700 or 1000 but Wowza Engine manager connections are increasing after every 5 seconds. Our streams are not being leeched as we confirm our traffic through analytics and wms stats. So wowza server is getting hanged when connections jump to 60000 and we need to restart wowza service again and again after 1-2-3 hours. We would like to fix that issue. Thank You
