With a rate of 1 coredumps per 3 minutes I'd rather hurry up to find the malbehaving application, seriously!
In lieu of moving the files after they show up, how about creating them in the right location immediately? Depending on the OS (which you fail to mention) there are various mechanisms to define how the core dump filename will be constucted. man core:
- The name of the file is controlled via the sysctl(8) variable kern.corefile (FreeBSD)
- ... the /proc/sys/kernel/core_pattern file ... can be set to define a template that ... to name core dump files (since Linux 2.6 and 2.4.21)

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.
