/usr/sap/KP1 directory filled up abnormally to 98%

Dear Sir/Madam,

Today the file size /usr/sap/KP1 has risen to abnormally to 98% of its capacity. Which remains at 45 - 55 %.

The DVEBMGS00 filled up abnormally. The " Work" directory under DVEBMGS00 filled up rapidly today morning at 8:55 AM.

I have allocate space to this file system.

Please advice why it was happened and what are the files ? Whether they can be deleted ? As sometimes core files generated and we delete them without any harm to the system.

I am giving the details of the listing of KP1 ( Our Production System)

1. cd /usr/sap/KP1

2. pwd

/usr/sap/KP1

1. ls -lrt

Any Pointer will be highly appreciated.
