[Rails] FastCgi

[Jacek Balcerski]

Hi,
I have a little problem with FastCGI. I use Apache with mod_fastcgi (not 
compliled in) ,
not gem fcgi. Everything work's fine, fast etc. , but every time when 
bigger sql statement or big html (don't know exactly)
realized fcgi became very slow or waits for 30 sec and then restarts ? 
Don't know what to do.
error_log from apache :
FastCGI: comm with server "../public/dispatch.fcgi" aborted: idle 
timeout (30 sec), referer: http://../contents/list
or
there was some error about terminated due error 15 or something but I 
have deleted my error_log and cant get this same error again

Anyway is there some way to eliminate this ?
