[Dovecot] Errors and periodic corruption using 99.10.5 release with mbox

Hi,

I'm seeing these errors in our logs periodically:

file istream.c: line 135 (i_stream_skip): assertion failed: (stream->v_size == 0 || stream->v_offset + count <= stream->v_size)

Timeout leak: 0x8069328

Any idea on what may be causing these? System is freebsd, format is mbox.

I'm also seeing periodic corruption of mailboxes. It's easily fixed because it's always a few stray lines of text left at the beginning of the mbox file above the From I'm currently trying to find out more about what actions may cause it.
