This sounds a lot like the problems we had, see ITS#5454. Replication
has been running smootly since we implemented the patch included there.
An alternative version is implemented in the CVS head release, but that
lacks a change from trylock to real mutex lock before the race condition
is fully closed.
We experienced a lot of replication problems after upgrading from a
slurpd based replication in 2.3.x to syncrepl in 2.4.8. We are
currently using the CVS head version (as it was about a week ago), and
most of our problems has been solved there :-) You should consider the
cvs version, as it has many syncrepl and syncprov fixes.
