   FriCAS classical integral timeout   
   03 Feb 17 17:52:19   
   
   For the trivial integration request:   
      
   \begin{axiom}   
   setSimplifyDenomsFlag(true)   
   integrate(sqrt(1 + p*x^2 - x^4)/(1 + x^4), x)   
   \end{axiom}   
      
   the FriCAS web interface runs into its five minute timeout:   
      
   Proxy Error   
      
   The proxy server received an invalid response from an upstream server.   
   The proxy server could not handle the request POST /FriCASIntegration.   
      
   Reason: Error reading from remote server   
      
   Apache/2.2.22 (Debian) Server at axiom-wiki.newsynthesis.org Port 80   
      
   -   
      
   But this is just another simple case of Euler's posthumous integrand   
   SQRT(a + b*x^2 + c*x^4)/(a - c*x^4).
