Resolution: Remove Crash Dump
Crash directory holds system crash dumps. As of the date of this release of the standard, system crash dumps were not supported under Linux but may be supported by other systems which may comply with the FHS. Debian has extended the standard for user space crashes as well via corekeeper to stores normal coredumps in subfolders of /var/crash. Removing contents of /var/crash can make the System program problem detected popups disappear on Ubuntu.
Step 1: Remove all the files in /var/crash folder or using command:
sudo rm /var/crash/*.*
Step 2: Reboot the system.
