Huge trace files with "LIBRARY OBJECT PIN" generated

Hello,

My DB version is 19.19 and I was contacted by our IT team about the fact they've been facing a lot of trace files on the DB server, which quickly fills up the space. Among those files some are huge (1Gb or more), and seem to contain information about the LIBRARY OBJECT PIN event.

For example, one of these file names is XXXX_ora_3923853.trc, and the contents looks like a repetition of package names experiencing a library cache pin, for example:
