Hello All,

I am working in a company in which we receive thousands of requests per day, when there are peek times, some of our weblogic servers reports the health status as "warning", we are using clustering and load balancing, i have searched for possible solutions on the internet but they all indicates the tuning of weblogic e.g increasing the time interval, stuck thread count etc etc.....

is there any solid solution available to this problem, means which could really solve this, i tried many of these but unable to solve the problem, every day to solve the problem i have to bounce back "restart the weblogic instance", so please help me in this problem so that i do not have to restart my weblogic server instance again and again.

your help is highly appreciated.

kindly share the following details to analyze the issue 1. Perm size and min and max heap size of weblogic server on which application was deployed 2. Ram size of server on wich weblogic was installed 3. When weblogic is in warning state, what message or error you are getting on web page and post the errors in logs also

Do you see stuck threads in your server(which goes to warning state) logs?

This won't be enough. Thread dump from your environment would reveal more if the threads are stuck due to the application deployed or network issue or maybe anything else.... get a thread dump when your server goes to hung state, the next time...
I agree. Here's the link:
