I just hit a spurious error which is inexplicable by my patches (none of my patches should have resulted in this):
kpropd[xxx]: ulog_replay failed (Unable to load requested database module ‘db2’:plugin symbol ‘kdb_function_table’ not found), updates not registered.
The only thing I can think of is the process may have been signaled with USR1, which resets the timer state (existing SIGUSR1 handler). That means there is existing code which is not signal-interruptible. All my patches were in the other process fork (the sub-process listening for full kprop messages; the only thing I do is signal the iprop process via the existing USR1 handler).
It also means if anyone ever sends a USR1 out-of-band, they might hit this condition.
