[Csync2] Database backend is exceedingly busy => Terminating (requesting retry)

[Samba]

Hi,
I could reproduce this issue with the code checked out from the trunk as
well.

Issue seems to be occurring when we have slow network [reproducbe at least
once in 5 times over a WAN ping response-times 300 ms; if i increase delay
to 1000 ms, then almost always reproducible].

I'm not sure why network speed (or rather slowness of it) would have any
impact on SQLite database transactions, since the database is accessed
locally within the same host.

I tried the option "-B" which is suggested over slow networks but that also
could not completely resolve the issue although occasionally it did reduce
the frequency of occurrence.

It would be great if any workaround [or if possible, a workable solution]
is  suggested.

Thanks and Regards,
Samba
