core dump file size
Hi All,
is there any way to find out the optimal/would be size of the cor dump file generated by the system while a process got terminated abnormally?
Basically we have been asked to provide the size of the core dump file being generated by the administrators who maintained the UNIX boxes. Currently it is 1GB but it easily exceed this allocated space. So we are looking for bigger suitable size.
Please helo advice.
Thanks,
Pushp.

crashinfo
CRASHINFO(8) BSD System Manager's Manual CRASHINFO(8)
NAME
crashinfo -- analyze a core dump of the operating system
SYNOPSIS
crashinfo [-d crashdir] [-n dumpnr] [-k kernel] [core]
DESCRIPTION
The crashinfo utility analyzes a core dump saved by savecore(8). It generates a text file containing the analysis in the same directory as
the core dump. For a given core dump file named vmcore.XX the generated text file will be named core.txt.XX.
By default, crashinfo analyzes the most recent core dump in the core dump directory. A specific core dump may be specified via either the
core or dumpnr arguments. Once crashinfo has located a core dump, it analyzes the core dump to determine the exact version of the kernel
that generated the core. It then looks for a matching kernel file under each of the subdirectories in /boot. The location of the kernel
file can also be explicitly provided via the kernel argument.
Once crashinfo has located a core dump and kernel, it uses several utilities to analyze the core including dmesg(8), fstat(1), iostat(8),
ipcs(1), kgdb(1), netstat(1), nfsstat(1), ps(1), pstat(8), and vmstat(8).
The options are as follows:
-d crashdir
Specify an alternate core dump directory. The default crash dump directory is /var/crash.
-n dumpnr
Use the core dump saved in vmcore.dumpnr instead of the latest core in the core dump directory.
-k kernel
Specify an explicit kernel file.
SEE ALSO
textdump(4), savecore(8)
HISTORY
The crashinfo utility appeared in FreeBSD 6.4.
