If you see an error like -bash: /sbin/free: No such file or directory, install the procps or procps-ng package:
sudo dnf install procps-ng # RHEL 9 / Rocky 9
In enterprise Linux environments—especially on x86_64 architecture running Red Hat Enterprise Linux (RHEL) or CentOS Stream—system administrators frequently encounter obscure error strings, process names, and memory reports. One such cryptic string is ms1542, sometimes seen alongside the classic memory reporting tool /usr/bin/free (or historically /sbin/free on older systems).
If you’ve run ps aux | grep ms1542 or checked system memory via free -m and noticed anomalies, this guide is for you.
An in-house application named ms1542 (maybe a build number or release ID) running on RHEL. Check with:
ps aux | grep -i ms1542
systemctl status ms1542 # if it's a service
ls -l /proc/1542/exe # reveals the actual binary path
cat /proc/1542/cmdline | tr '\0' ' '
strings /proc/1542/environ
