We have used that process.
When WebSphere is processing a transaction it initiates many sub processesor child PIDs. These are not seen with SAR or the PS command. They will show up when using STRACE -f. Some of these child processes have futex, FUTEX_WAIT, FUTEX_WAKE, SYS_7, SYS_195, etc in the trace output. We are trying to determine is any of these systems call could be causing our performance problems.
