Log is not generating for this, also port is used only for this. Please find the below details for more info.

One of our web application is running in Linux and using apache web servers. Application is hosted in port 4080 (for soap requests) and port 9999, and its serving behind a vip and cname. Initially it was working fine in another server and recently (2 months back) we have moved to the new server and from there onwards often ports 4080 and 9999 are failing.
As per our analysis there is no problem in the load balancer where the vip is served and also we didn't see any issues in the apache/application logs. But after checking with networking teams we found that at the time of port failures, health check (status.html) for the vip is failing and that causing the issue. Sometimes within 5 mins ports are coming up automatically without taking any actions and sometimes its not coming up and we are restarting the apache services.
We could not able to figure out whats the problem here, could you please someone help me how I can find the root cause of the issue.
