Hello @Swaroop Gowda D,

On an Azure Linux VM, issues related to libc.so.6 typically indicate a problem with the glibc library, which is essential for basic system operations. Here's how to troubleshoot it:

Filesystem mounted with noexec

Cause: Prevents execution of binaries or shared libraries from the affected filesystem.

Action: Remount the filesystem without the noexec option if necessary:

sudo mount -o remount,exec /path/to/mount

Try to reinstall glibc using your package manager:

sudo yum reinstall glibc  # for RHEL/CentOS
sudo apt-get install --reinstall libc6  # for Debian/Ubuntu

Check disk health: dmesg | grep -i error

Run memory tests or consider redeploying the VM if corruption is suspected.
