I had nearly the same issue. The only way to make it work again was to set
it up new

Betreff: Re: [Samba] sudden replication failures
Nope, it seems that I have problem with another bug. In my case samba
process drives cpu to 100% (one core) and the output of strace is something
like this repeating itself indefinitely:
fcntl(10, F_SETLKW, {type=F_RDLCK, whence=SEEK_SET, start=16836, len=1}) = 0
fcntl(10, F_SETLKW, {type=F_UNLCK, whence=SEEK_SET, start=16836, len=1}) = 0
and opened filed descriptor pointed to main domain tdb file (samdom.com.tdb)
Next time it happens I'll try to do a core dump and submit a bug.
