Re: slapdd running at 100% of the cpu?

[Aaron Richton <richton@nbcs.rutgers.edu>]

Take a core snapshot of the process with gcore (or just attach with gdb, 
if you don't need to get things running quickly) and get a symbolic 
backtrace. On FC5, you probably need -debuginfo to get useful backtraces.

I've reported at least one livelock since 2.3.19 (ITS #4738). That would 
show up as 100% CPU, if it hit you. An update has been released for about 
a month; upgrade OpenLDAP to 2.3.30.
