Question

What are the rts32 processes seen in "top" and elsewhere?

Answer

The rts32 processes are Run-Time System, 32-bit processes. RTS typically deals with details of the interface between a program and the operating system, such as, system calls, program start-up and termination, and memory management.

Usually the persistent rts32 processes seen in "top" are associated with ue_nn daemons (for example, ue_01, ue_21, etc.)

Do the following to see what function each rts32 process is associated with:

In "top", note the process number (nnnnn) (the first number, the number in the PID column), then

> ps -ef |grep nnnn

<where "nnnn" is the process number>

This will show the function the rts32 process is associated with (such as, ue_01, ue_21, etc.).
