Namely, your GC doesn't work because of the issue and NILFS2 volume has exhausted yet. As a result, the file system is remounted in RO mode. Messages about discarding dirty pages take place after remounting in RO mode in the case of trying to flush dirty pages. Sorry, unfortunately, I have the crazy month and I can't find opportunity for investigation of the issue. I hope that I'll have such opportunity soon.
