Bug #1672

Updated by tuxillo almost 10 years ago

Using 2.4.1 with the lone patch from http://bugs.dragonflybsd.org/issue1583

 ... I'm not sure when this occurred; possibly during nightly cleanup. 
 
 The previous evening gave HAMMER a little more stress than usual via a bit of 
 
 `undo` usage (normally none) which did seem to be turning up transient(?) 
 
 "ITERATE ENTIRE HISTORY: Unknown error: 0" results similar to 
 
 http://leaf.dragonflybsd.org/mailarchive/users/2009-09/msg00062.html (but here 
 
 the HAMMER config is left at the sane defaults).    Not intending to poke at them 
 
 too much unless it relates to the panic here. 

 

 Couldn't get a dump because I didn't realize I hadn't specified a dumpdev (doh!).
