Hi All,
I need some help in debugging a package installation failure. Initially I thought it’s scriptlet failure, but the rpm child process of zypper seems to be exiting with 0 and staying as . Not sure what’s the culprit here.
process list:
root 3856 2618 0 10:06 ? 00:00:00 \_ sshd: cloud-user [priv]
cloud-u+ 3878 3856 0 10:06 ? 00:00:00 | \_ sshd: cloud-user@pts/0

Could you please help me in understanding the failure. I have strace output of all the child processes.
Below is the strace of zypper process (pid 4486) after the exit of rpm process:
poll([{fd=22, events=POLLIN|POLLERR|POLLHUP}], 1, 5000) = 1 ([{fd=22, revents=POLLIN}])
read(22, "+ exit 0\n", 4096) = 9
fcntl(22, F_GETFL) = 0x800 (flags O_RDONLY|O_NONBLOCK)
fcntl(22, F_SETFL, O_RDONLY|O_NONBLOCK) = 0
fcntl(22, F_GETFL) = 0x800 (flags O_RDONLY|O_NONBLOCK)
fcntl(22, F_SETFL, O_RDONLY|O_NONBLOCK) = 0

Installation with rpm package manager is getting completed without any issues.
