As far as I know on linux the threads are shown as different processes.
85 threads is a high but not an unusual value.
We are having the similar issue where we are seeing multiple run.sh process are getting created while starting the jboss application server on linux. We have not seen any issues with the applications though. We have another similar linux server where the same instnace are runing as they are loadbalance, however we dont see the similar issue on the other server. Any help or suggestions are appreciated.
