Has anyone had a problem with texvc hanging when trying to render math within a wiki page? My installation was working fine until yesterday when updates to pages including <math> would hang forever. Looking at the processes owned by apache on the server, I can see:

./math/texvc sh -c convert convert

in addition to the other httpd processes. Any ideas? I've tried running texvc from the command line and get the following output until it hangs:

$ ./texvc ~/public_html/testing/ ~/public_html/testing/ 'E(C_R) = - \frac{1}{\log q} \sum_{i=1}^q \frac{n_r^i}{n_r} \log \frac{n_r^i}{n_r}' iso-8859-1 This is dvips(k) 5.86 Copyright 1999 Radical Eye Software (www.radicaleye.com) ' TeX output 2005.02.09:0842' -> <texc.pro>. [1]

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. Running texvc from the command line also forks a 'convert' process that hangs.

any advice?
