System encounters multiple VCS resource timeouts and agent core dumps (3424429)

Last published : Sep 18, 2026
The system encounters multiple VCS resource timeouts and agent core dumps without any specific reason.
The issue pertains to a hardware errata with the Intel Xeon CPUs where a processor can go into a low power sleep mode, but takes a long time to wake up. This can cause erratic scheduling behavior, leading to unexpected delays, expired timers, or occasional freezes. For more information, see the Oracle document: BugDisplay?id=15659645
Workaround: Add the following lines to the /etc/system file and reboot the system:
set idle_cpu_prefer_mwait = 0
set idle_cpu_no_deep_c = 1
