Sorry, the attached dmesg doesn't contain the transaction abort message.
It only has the flooded ENOSPC from enospc_debug option.

Sorry, forgot it's not calling btrfs_abort_transaction() but
btrfs_handle_fs_error(), thus no backtrace.
Then it's too many pinned bytes from dropped snapshot caused the problem.
And since we're holding one transaction without ending it, it prevents
ticketed space system to flush and free space.
It looks like the check in should_end_transaction() is not good enough.
Maybe Josef and Nikolay could have some better ideas on this?
Thanks,

Were you performing any specific operation when this happened or you had
simply deleted a snapshot and some time later you got the ENOSPC?

It does something like this if it matters: It creates a chain of
snapshots and writes only to the one it last created, while sometimes
deleting files from older snapshots in the chain. It has max 5 snapshots
in the chain and every ~60min creates a new one and later deletes the
oldest. For example it has a_1, a_2, a_3, a_4, a_5 (a_2 being a
writeable snapshot of a_1) and writes only to a_5. Then it snapshots a_5
to a_6 and then only writes to a_6 and later deletes a_1.
Looking at the latest ENOSPC that occured at 3:55, it created the latest
snapshot at 3:05 and deleted the oldest at 3:48. It wrote to the latest
snapshot while it dropped the oldest.
