Retained memory for a corrupted deferred kernel dump cannot be cleared
(Doc ID 2472724.1)
Last updated on JANUARY 13, 2025
Applies to:
Solaris Operating System - Version 11.3 to 11.3 [Release 11.0]Oracle Solaris on x86-64 (64-bit)
Oracle Solaris on SPARC (64-bit)
Symptoms
A system running Solaris 11.3 exhibits a low memory condition.
A previous crash dump image is preserved in memory
The ::memstat output as shown in the Explorer output under disks/zfs/mdb/mdb-memstat.out or as captured by the command:
# echo ::memstat -v | mdb -k
would look similar to this:
The /var/adm/messages file might contain entries like the following:
savecore: [ID 702911 daemon.error] bad magic 80bf0000
That is an indication that a deferred kernel dump residing in memory is corrupt from savecore's point of view and as such savecore cannot process that dump.
