About the services we are using: oxauth, oxtrust, identity and passport.
About the top command detail: After execute the ps ef | grep "pid", we found that the jetty service is the oxauth service. The same that we modified some time ago to increase the xmx and xms parameters.
As I said before, some time ago we had been experienced server outages each day, when the outage came, the CPU usage increased to 170-180%. Now, we have been experienced server outages each 5-6 days, when the outage comes, we check the top command and we see that jetty service (oxauth) is using 170-180% cpu. After we restart the services, the jetty service backs to normal. It's like the jetty service is accumulating the usage of cpu, each day is higher than the last one until the server outage occurs.
