have you tried to repair/regenerate the database?

The OS is on the C drive. we have allocated 90gb to NEW with an age limit of 8 hrs.
This has worked fine until last night when we got cannot write messages in the status.
Upon looking at the the BI5 folder I saw that the file clips.dat in the db folder had reached 76gb.
How big will this file get?
How do I control it and set limits so it doesn't eat up the C drive?

The 'New' folder will get as big as 90gb that you set for the 'New' folder. But... with a 250gb C: drive, there probably isn't that much free space. Windows will use additional storage for Restore Points, temp files, and, Windows updates - as well as space for User folders and data.

Do not put the BI database on the C: drive! Windows hits that drive enough - you don't want several continuous streams recording to the C: drive - it will effect Windows performance (even on a ssd drive?). Use a separate drive for the BI db.

Note: I have a 2tb ssd drive exclusively for my C: drive. I've turned off as many Windows logs as possible to reduce I/O to the drive. I've always done this for performance - even when I used hdd.

Upon looking at the the BI5 folder I saw that the file clips.dat in the db folder had reached 76gb.

76GB That doesn't sound right. My clips.dat is presently at 653MB which seems far too big, but yours needs help. Send an email to Support !

As said by others, I also keep the BI5 files away from C: drive. I have a 250GB SSD only for BI5 db and New folder, and a WD Purple for the Stored folder.

mine was on 21gb until i run the repair/regenerate database, that is why i suggested that as an option. got to be worth a try.
