[krbdev.mit.edu #7784] krb5-1.12 beta2 - kpropd ulog_replay failed error

[Richard Basch via RT]

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.
