Strange state returned with ps

[Bastos]

Hi all

I rather often get some probs with qmail : some of its processes fall in the 'U' state, i.e. they do nothing and I can't kill them and they don't launch themselves again.

I read the 'man ps' but there is no reference to the 'U' state.

Does anybody know what this state is and how I can get rid of those processes?

From now, the only way I can go on working with qmail is to reboot my server and this solution s***s a lot!

Thanks in advance

If this can help, here is a solution which seems to fix my problem : in /var/qmail/control/, I created a concurrencylocal file and a concurrencyremote file, both containing the 1 (one) value.

With those files, Qmail works only on one delivery in each way (in and out) at the same time, so it slows reception and sending, but it seems to avoid a problem due to HFS+...

Anyway, I still don't know what this 'U' status means and how to get rid of it.

Any clue?
