Hi, all while investigating periodic jobs failure, I mentioned a lot of Z processes on undercloud:
bash-4.2# ps aux | grep " Z " | less root 28481 0.0 0.0 0 0 ? Z 17:41 0:00 [instack-haproxy] <defunct> root 28494 0.0 0.0 0 0 ? Z 17:41 0:00 [instack-haproxy] <defunct> root 28509 0.0 0.0 0 0 ? Z 17:41 0:00 [instack-haproxy] <defunct> root 28522 0.0 0.0 0 0 ? Z 17:41 0:00 [instack-haproxy] <defunct> ... bash-4.2# ps aux | grep " Z " | wc -l 979 About a thousand same zombie processes. I don't think it's appropriate behavior, although not sure it's the reason for failing jobs. Any ideas why it could happen? Thanks -- Best regards Sagi Shnaidman
