[Serusers] defunct process

Hello All, I have installed ser-0.8.11pre29-1 on RedHat 9.0. When I start ser by script /etc/init.d/ser or directly using /usr/sbin/ser, the process SOMETIMES hangs at the Aliases line show below. When I list the process table, I observed there was a defunct process. Now, this does not happen ALL the time when I starts ser. Sometime, /use/sbin/ser or init script will start fine without a hiccup. I also notice that the defunct process is ALWAYS the second lowest process id among all ser processes. Can this be a case of race condition for the parent process to exit without waiting for the child? I did not encounter this using ser-0.8.10 on RedHat 7.3. However, I do remember encountering this behavior once when running ser-0.8.10 on RedHat 9.0, I have removed 0.8.10 and installed 0.8.11 since then for testing 0.8.11. Could this be a problem of RedHat 9.0? Is anyone experience this or am I the only one?
