Firstly check the contents, usually they are just logs about activity on IMSS

if they are Logs you can delete them if not then its best to leave them be, most of the time they are just activity logs but now and then you will find that they contain info about system errors

Uncle,

How I know this is just normal activity log? I'm remotely from the server, and there are quite a number of such files, in which most of them in the size of 33 Mb.

did you find the type of content is in the files? you may try to see if these are text files or binary files.

You may run the command

file core_server_imssmgr*

if you are notr sure what are these files and you don't to keep them you may archive them to tape and the delete from disk

If these are true core dumps, you can check this using the command

adb filename

If this is a core file, adb (or mdb) will recognise it. If so, you can safely delete those files, these are only useful for the software developers to determine why their software has crashed.

Getting so many core files in such a short time means that the IMSS processes crash a lot. Perhaps you should investigate if any more recent versions of the software exist.

I agree with omarfarid, just compress these files and preserve that in your backup and then delete from disk. If you feel any challenge after deleting those files then you can just restore them from your backup.

(provided these are true core files): Getting so many core files in such a short time means that the IMSS processes crash a lot. Each process crash corresponds to a core file that contains a dump of a crashed process.

if you want dignose of these core file or you want it to send support vandor, you should not delete these file.

These file are no where in use, you can treat as a log files.
