Unknown Core generated under "/" on HP-UX 11iV3
Hi,
On our customer system with HP-UX 11iV3 , a core file is generated under "/".
But i am not able to get any information of the core , "file core" command is not showing which process has generated the core .
#file core
core: ELF-32 core file - IA64
How can i findout which program has generated this core ?
Also attaching the "strings core" output.
Regards
Abhilash

Why do you care? Just remove it and move on. If nobody confesses to owning or caring about it, why should you?
How old is it? What is it's size?
What does this show:
elfdump -o -S core
It seems the core was truncated.
At the end it has these strings:
../../snmpd/shared/dosnmpv3.c
snmpdm: SrDoSnmp: SNMPv2 request in v1 packet ?
/etc/srconf/agt/snmpd.cnf
/etc/srconf/agt/snmpd.jnk
_=/usr/sbin/snmpdm
So it looks like: /usr/sbin/snmpdm

Re: Unknown Core generated under "/" on HP-UX 11.31
Hello Dennis,
I am not worried about the core , but on customer setup its creating problem because the root filesystem is getting full when the core is generated. Customer is behind me...:)
Following is the output of the command which you requested.
INP ocsdt10:/u01/backup/TSF-PM00015632-RootFileSystem-Full#elfdump -o -S core

Well, if you don't want them, you can do:
1) mkdir /core
2) coreadm(1m) to redirect corefiles to another location.
3) ulimit -c to limit corefile size.
The first is probably easiest.

The file has been truncated, so next to useless.

Re: Unknown Core generated under "/" on HP-UX 11.31
Hello Dennis,
I used the coreadm command to set the global core file path. The output shows like below.
Will it redirect all the cores generated by the proecesses to the defined path ?
# coreadm
global core file pattern: /var/adm/core/core.%p.%n.%f
init(1M) core file pattern:
global core dumps: disabled
per-process core dumps: enabled
global setid core dumps: disabled
per-process setid core dumps: disabled
#
Does it require system reboot to make this changes to effect , or am i missing something here ?
Still the cores are generated under "/".
Thanks and Regards
Abhilash

No reboots required. I assume you need to enable the "global core dumps".
