I am seeing a few "Failed to write session data (files)." session errors each day. Even though we have housands of our sessions working fine every day, a few fail with this error and I can't tell why.
The disk's partitions have plenty of room, the directory pointed to by session.save_path exists and does not contain too many files, and, again, thousands of sessions work fine every day.
Where can I look for clues as to why this is happening?
Thank you!
