Never finish fetching inventory

[AdamMirko]

Greetings.

After the server issues last week my inventory has never finished fetching all items (talking only 4000 items here), possible before as well, but didn't pay attention to it.

When I log in viewer will say it finished (Firestorm + Standard), but if I then search for "a" it might start again, if I wait a few hours, it will say it finished, then "b" might start again etc. I can do a-z, and they will not start a new fetch (until next time the server goes boom) but longer strings might still give a fetching message.

Is this normal behavor? If not any hints on how to locate defect items?
