samba - Mar 2005 - Problem with 3.0.10 and 3.0.11 with 1 smbd process using 99% cpu

I've been having problems since updating to samba 3.0.10 on Debian 3.1
Below is the output of ltrace and gdb on the offending smbd process.
I tried upgrading to 3.0.11 and the problem still exists. Anyone have 
any suggestions?


[ltrace output]
After about 20 seconds on the processes ltrace loops this

iconv(0x82cecc8, 0xbffff218, 0xbffff21c, 0xbffff220, 0xbffff224) = -1
__errno_location()                               = 0x403ac560
iconv(0x82cecc8, 0, 0, 0, 0)                     = 0

There were a lot of printing fixes in 3.0.11.
I would really suggest an upgrade.  Particularly due
to loading issues like this one.

Just to let everyone know I was able to fix the problem. I cleaned out 
the tdb files which appearntly had been corrupted.
