Re: memsize ferret error

[Jonathan Callahan <Jonathan.S.Callahan@xxxxxxxx>]

Peter,

It would be helpful to know the following:

• version of LAS
• precise LAS request (xml request object)
  
• ncdump -h of the data file

With these we should be able to come up with similar tests at our end to try and mimic the problem.

Of course, having access to your LAS is very useful so that we can see the problems.  And putting the las/etc/LASinfo.pl (<6.3) or las/bin/LASinfo.pl (>=6.3)  cgi script in las/server/ will allow  us to do some debugging remotely.

Hi Phil,

        I have had the same problem with the LAS server I have setup. I
adjusted the ferret memory size and that helped but did not solve the
problem. I am having some difficulty understanding why Ferret seems to
need large amounts of memory. Perhaps some others who have more
experience with  LAS and Ferret could provide some guidance about how to
determine Ferret memory requirements?


Cheers

Subject: memsize ferret error

Hello,

With some help from others, we have identified some errors that we have
been getting on our LAS server. 

It was suggested that we modify the memsize within the ferret scripts
and see if this helps. 

We are upgrading the physical memory of the machine, as we have
identified a need to do this anyway. However, I am curious if anyone can
pin-point the following error.

 **ERROR: insufficient memory: 27324000 words were requested.

Will adjusting the memsize in the ferret scripts help resolve this?

I have a few ideas but would like any suggestions from the experts prior
to making the adjustments.
