Opened: May 13, 2020
Severity: 3-Major

Symptoms

In certain instances, the iqsyncer utility may not write the core file for system signals.

Impact

The iqsyncer utility does not write core file.

Conditions

-- SELinux policies enabled. -- Run the iqsyncer utilities to initiate a core dump with system signals SIGABRT, SIGQUIT, and SIGSEGV.

Workaround

Disable SELinux with 'setenforce 0'. You can now generate a core with a SIGQUIT (-3), but not with SIGABRT or SIGSEGV.

Fix Information

None
