Since few days we see that the Integration Server ( running on Linux ) is utilizing high memory…it is set with max 2GB java heap…in the same environment we have another identical Integration Server ( on another Linux virtual server )with the same configuration and custom packages and that is working fine.
when the memory utilization goes high even with not much heavy traffic…the swap process on the linux comes into picture and also the io% becomes abnormal and it doesn’t come down.
If we kill the integration server process and then suddenly the io% comes to zero and everything appears normal on the virtual machine. This indeed tells us that there is something fishy with the Integration Server and that’s the same argument that the Infrastructure team ( Unix admin ) say.
Did check and done everything possible to see if any particular package or service is causing trouble or anything else in the config parameters. Was unable to identify anything. As mentioned in the opening para, the other identical integration server with same version, fix level, deployments is working perfectly normal.
Did anybody notice such issue ? or can help me with this.
