Hmm... rereading a debuglog file, I noticed that you leave the default value – 20 MB – for "palette pool" in videosettings. At this level, heavy filled with derelicts, that may be not enough (generally, towards the end of the game with widespread use of salvaging, pool for unpalettized textures can exceed 50 MB). Try to increase this value at least to 64 MB.
