Occasional Core Dump
Hi,
We have one application (c language) installed on our AIX 5.2. When we enter some large amount of data in one screen and do update, it is dumping core some times without any error (like bus error, segmentation fault). Next we open the application again and enter the same data and do update. This time updates go through fine without any problem.
This problem (core dump) is happening only with that particular screen and occasionally, not always for the same data update.
We tried the same on another machine. It is not dumping core on that. Updates are going through fine always.
What could be the cause for this problem? Is this problem due to some memory settings? How to troubleshoot this problem?
Please help ...
Thanks,
Venkat.

Hi guys,
just want to know which core file pattern is best to set for core dumps:
1) per-process file name pattern
or

I will really appreciate an explanation why the chosen one is better.
Thanks a lot guys. (2 Replies)

pcapdump
pcapdump(1) pcapdump(1)
NAME
pcapdump - dedicated packet capture utility
SYNOPSIS
pcapdump [OPTIONS]...
DESCRIPTION
pcapdump captures packets from a network interface and writes them to a dumpfile. The filename argument given to -w will be formated by
strftime(3).
PCAPNET OPTIONS
-i interface
Input interface to read packets from.
-r pcap file
Dump file to read packets from.
-w pcap file
Dump file to write filtered packets to.
-f expression
BPF expression which selects packets to be filtered.
-s snaplen
Capture snaplen bytes of data from each packet.
-p Disable promiscuous mode sniffing.
PROGRAM OPTIONS
-u owner
Set the output file's owning user to owner.
-g group
Set the output file's owning group to group.
-m mode
Set the output file's mode to mode, specified in octal.
-t secs
Dump file rotation interval in seconds.
-c count
Exit after capturing count packets.
-T secs
Exit after capturing during this amount of seconds.
-H Only capture link, network, and transport headers; do not capture application-layer data.
-S sample value
Sample the packet stream by only dumping 1 in every sample value packets.
-R Together with -S, sample the packets randomly, not systematically.
-P pidfile
Daemonize the process and write its PID to pidfile.
-C config file
File to read configuration variables from. Instead of passing configuration through the command line, a file can be used to specify
values for the bpf, device, filefmt, group, interval, mode, owner, promisc, and snaplen options (not all need to be specified; de-
faults will be used otherwise). See /usr/share/doc/pcaputils/examples/pcapdump/eth0 for an example.
