Thanks for the response RMG.
No It is not Prod…it is one of our test environment. I cannot bump it to 5000M as the total memory allocated to the machine is just 4096M…Done multiple restarts and even it takes lot of time to stand up…definetly IS is not getting enough memory to load all packages and save the config files.
As part of my investigation, I just noticed something…when I killed the IS process ( the only wM process running on the machine ) and did a top on the linux machine, to my surprise I could see that the memory utilized on the machine was still 72% . Ideally there should be nothing else on this machine apart of wM IS process that should run. So , going by this there is something that is utilizing the RAM. Just posted this info with screenshots to the infra guys, let me see what they come up with.
Thank you.
