I haven't had any augs cause that problem so far on my server and I have a decent amount available. I do know that there are issues with inserting Lore augs sometimes that are already on another piece of gear, but I haven't heard of it causing a crash. Normally, it just makes the item so that it can't be removed from the aug pool.
Maybe post the stats and any special attributes of the aug. And, have you confirmed that it happens every time with that particular aug, or just sometimes? Also, have you tried the same aug in another piece of equipment to see if it still happens, or is it only certain combinations of augs/items? I would think that there might be issues with having multiple worn/click/focus effects on a single item. Could that be the case? The augs I use are only hps/mana/end and maybe +damage or +shielding/accurace/etc.
