[LON-CAPA-users] catching maxima errors

[Peter Dencker]

Hi,

I'm summing up my knowledge about the problem:

1. using customresponse with maxima:
      "CORRECT" and "INCORRECT" work;
      a maxmima syntax error causes: 'Internal error .."

2. with <mathresponse> there is no problem at all, but the 'BAD_FORMULA'
return takes more time than a "CORRECT" or "INCORRECT" return

3. working on servers of other domains ('fhwf', 'nsu') works fine,
   with one exception: ohiou
   sometimes it bombs, sometimes it works, examples:

worked: 01:44 pm (CET), but

#########################
scl/dencker/testing/mini.problem
Thu Nov 29 01:35:07 pm 2012 (CET):
Code ran too long ....
The error occurred on host ohioua4
#################################
Thu Nov 29 01:38:06 pm 2012 (CET): ...
This error occurred on machine ohioua6
#################################

   on scll1 it never works

4. The restart of"loncontrol" has not changed anything. No error massage
occurs:

[root at lon-capa ~]# /etc/init.d/loncontrol restart

lond            started
lonc            started
lonmaxima       started
lonr            started

5. Trying 'x)' on maxima on the server gives the english error massage
'incorrect syntax: Too many )'s'.
