savecore fails on Solaris 2.6 with 2GB or larger swap partitions

Published 29 Nov 1999 Read time 24 sec(s) (2929 views). Solaris

There is a known bug in Solaris 2.6 where a system will not write out a core file even though savecore is enabled.

This occurs on systems with 2GB (4194272 blocks) or larger swap partitions.

Running savecore manually causes it to fail with the error "magic number mismatch".

This problem has been corrected with Solaris patch 107490-01 and is included in the Solaris 2.6 Recommended patch cluster.

NOTE: Installing the patch is safe even on a system with less than 2GB swap partition.
