Description Jonathan Elsas 2005-02-09 17:34:24 UTC
when rendering math in an article, the browser window hangs indefinitely, waiting on a response from the server.  While 
this is happening, the following processes are owned by apache (in addition to the httpd processes):

    ./math/texvc /home/jelsas/public_html/wiki/images/tmp /home/jelsas/public_html/wiki/images/math C_r utf-8

    sh -c convert -quality 100 -density 120 /home/jelsas/
public_html/wiki/images/tmp/ /home/jelsas/public_html/wiki/images/
math/8e0e87530ca474ad4fe02b49f27a0e33.png >/dev/null 2>/dev/null

    convert -quality 100 -density 120 /home/jelsas/
public_html/wiki/images/tmp/ /home/jelsas/public_html/wiki/images/

Running texvc from the command line gives the following output until it hangs:

$ ./texvc ~/public_html/testing/ ~/public_html/testing/ 'a^x=b' iso-8859-1
This is dvips(k) 5.86 Copyright 1999 Radical Eye Software (
' TeX output 2005.02.09:1226' -> 
<>. [1]

at this time the same processes are hanging (texvc, sh, and convert).  Several temp files are generated, ending with .dvi, 
.aux, .log, .ps and .tex.  The .ps file does look like the correct rendering of the formula, so I'm guessing the TeX/LaTeX 
piece is completing successfully.  

I'm using ImageMagick version 5.5.6 and MediaWiki version 1.3.9.

update: upgrading to the latest version of ImageMagick (6.1.9) seems to fix the problem.
