[daip] FRING on large (25Gb) line dataset problem

[Kazi Rygl]

Dear Mark Greisen,

I encountered a problem with FRING when I run it on a large (25Gb) VLBI line
dataset.
On smaller datasets it works fine. Also the problem is only there with the
TST version, not in the NEW version. I tried decreasing the solint parameter
but it didn't help (see suggestions of AIPS output below).
Setmaxap says:
>setmaxap(0)
AIPS 2: SETMAXAP: current max dynamic AP is   528.000 Mbytes
AIPS 2: SETMAXAP: allowed range is  20 to  1536 Mbytes

Since I'm not sure why FRING crashes (local problems, or due to something in
the program) I thought I just report it. Last week I could run FRING with
similar inputs without any problems.
I paste the output of AIPS below together with my inputs.

Best regards,
 Kazi
