Redis-server is a zombie process

Hello,

i’m running deepstack, using this image - deepquestai/deepstack:arm64
i found out that there is a zombie process

anubisg1@czsrc-lan-srv03:~$  ps aux | grep 'Z'
USER         PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
root        3483  0.0  0.0      0     0 ?        Z    Mar25   0:00 [redis-server] <defunct>
anubisg1 3376083  0.0  0.0   7692   672 pts/0    S+   11:07   0:00 grep --color=auto Z


anubisg1@czsrc-lan-srv03:~$ pstree -p -s 3483
systemd(1)--------containerd-shim(3343)--------server(3440)--------redis-server(3483)

redis-server is forked by server , and server is the entry point for deepstack.
i cannot find any thing in the logs, except for :

OpenBLAS Warning : Detect OpenMP Loop and this application may hang. Please rebuild the library with USE_OPENMP=1 option.

Happens to me as well,
Is there a way to use external redis server for next version?
