Performance on GF v2.1.1 degrading everyday at same time
I am a new server admin and I look after applications that are posted on Glassfish Enterprise server v2.1.1 Oracle Solaris 10 8/11 s10x_u10wos_17b X86 ( 5.10 Generic_150401-01 i86pc i386 i86pc).
For the past two weeks the application stops responding totally between 5PM and 9PM. The application receives ussd requests and getting average of 70 requests per second. I have used visual vm to try and spot where the problem is but cannot find anything. During that time the top command show memory and cpu usage still very low aswell as the average load.
Kindly help out.
