I've seen it also but I gave up trying to find a fix and implemented
another mechanism for saving user deleted mail.

Hex dump of a faulty cyrus.expunge problem that caused core dumps.

      0000  0000 0047 0000 0000 0000 0007 0000 004C [...G...........L]
      0010  0000 0048 0000 0000 44C2 575A 0000 0115 [...H....D.WZ....]

      0030  0000 0000 0000 0000 0000 0000 0000 0001 [................]
      0040  0000 0000 0000 0000 0000 0000           [............    ]

If I remember correctly, one of the 0 fields winds up being
decremented, or some number subtracted from it, creating an completely
bogus value. cyr_expire would core when it indexed into the mapped
cache file.  I think the core was in this loop in process_records().

   /* Compute size of this record */
   cacheitembegin = cacheitem = mailbox->cache_base + cache_offset;
   for (cache_ent = 0; cache_ent < NUM_CACHE_FIELDS; cache_ent++) {
            cacheitem = CACHE_ITEM_NEXT(cacheitem);
   }

cacheitem would wind up off in space.

This was with very early 2.3 code so whatever I saw may not be what
folks are seeing now.
