This morning I see on one of our monitors that we have a server with the filesystem /phrases 100% full. Looking at it, I see 4 phrases*.icp files which are big and were created around midnight. I asked the previous operator what was running at that time (batch processing transaction files) and from what he told me, I do not see the relation with this.
Can someone tell me what those files are for and why they were created ?
Is it safe to delete them ?
