Sudden spike in TLogQueueCommitSlow warning

I noticed that in one of my clusters the number of warning message for TLogQueueCommitSlow has just jumped a lot since ~24 hours. To my understanding nothing has been changed in the cluster and I’m using PV using the disk.csi.azure.com driver.
I saw this post:
FDB degraded log processes. What does degraded mean?.

I’m wondering what else than the drive being slow could cause this warning ?
