Need to confirm the core file deletion

Hi Gurus,

It may be rubbish querry.But I need to ask you urgently.

I have a core file in /opt FS. not sure whether I can remove it or not.

[root@server1:/opt]#file ./hpsmc/avc/bin/core
./hpsmc/avc/bin/core: core file from 'monitorsvcd' - received SIGABRT
[root@server1:/opt]#

Could you please suggest.
NB.The node is a cluster node.

By the by how can I confirm who /which application is using this file currently?

Pls advice ASAP.

Thanks in advance.

Yes you can remove core file. Its created when some program got SIGABRT signal.

lsof | grep -i hpsmc/avc/bin will show, which are the binaries now opened & which are the process id's for each, which will give some clues which application using these.

How old is it? How often do you get one? Do you have support for monitorsvcd? What does "file core" show?

You may just want to remove it.

Nobody but you. Once a core file is created, it isn't accessed until you use a debugger.

"whether I can remove it or not."
----You can remove it safely if you dont have intention to get it investigated by the developers who developed the process which dumped it.
Its from process called monitorsvcd.
"who /which application is using "
----You can use lsof to list handles on this file. You still need to download as its not bundled with Hp-UX

Re: Need to confirm the core file deletion

hi,

if you dont use a debuger to analyse what was the problem for core-dump them you could remove the file.
