[daip] FRING abort, 31DEC10

[Dieter Engels]

Dear colleagues, we recently installed AIPS version 31DEC10 to work with
an EVN dataset. The dataset contains observations of a stellar maser using 
backends with 2048 channels. FRING aborts with ZABORS: signal 6 received, 
if we do not diminish the bandwidth (setting BCHAN and ECHAN). Sometimes
also "signal 11 received" is communicated.

FRING was tested on  Linux Ubuntu 8.04 LTS and Linux Ubuntu 10.04 LTS 
sytems. The error does not appear, if we use our ancient 
AIPS installation 31DEC04.

FRING parameters:
>default FRING
>getn 1
>calsour 'J0121+1149', '3C454.3', ''
>bchan 1
>echan 0
>docalib 1

>aparm(3) = -1
>aparm(7) = 7.0

>dparm(2) = 1024000
>dparm(3) = 500.00
>dparm(4) = 0.00
>dparm(5) = -1
