ZONE - /var file system has not enough space to grow crash filesystem

we have zone configured solaris 10 server.

It throws the alert message of "panic". The error message is "not enough space in /var/crash/<servername>"

From the du -sk command, i found crash directory occupies more space. I dont know what are the files are unnecessary for deletion. The files are listed below,

-rw-r--r--1 rootroot1161894 Feb 28 20:26 act.0

-rw-r--r--1 rootroot2 Feb 28 20:26 bounds

-rw-r--r--1 rootroot1594567 Feb 28 20:21 unix.0

-rw-r--r--1 rootroot6444326912 Feb 28 20:26 vmcore.0

Please help on this.

Thanks in advance

None of those files are necessary. They are the crash dump put out when the machine crashes to help diagnose why it crashed.

So if your not trying to diagnose a source of crashes, then they can all be deleted.

But if your machine is crashing and your trying to work out why, you need to get more space so it can write them out properly.

Thanks Robert.

I have a doubt, why those files are suddenly growing. but,

recently we were trying to upgrade the processor and memory.

shall i remove those files manually or it will automatically deleted in future.

I don't think their deleted automatically. Delete them manually..

they are not deleted manually. So you can delete them.

But as Robert said if you are trying to fugure out why the server is crashing the vmcore is usefull.
