RE: Panic info

 Hi Brian,

It is very much possible that lis_down is called from a put routne
indirectly. Definitely, I am not using lis_up and lis_down.

I did not get a chance to work on this, I will check this, sometimes
this week.

Will you be releasing LiS-2.18.1 anytime soon?

Thanks
Ed

Rodrigues,,

If I follow this right, it looks like you are calling (directly or
indirectly)
lis_down from a put procedure.  Did you ever get to the bottom of this?
