   My installation of MyMDR will show "500 internal server error" from time to time in a random manner. Normally the report can run with no problem at all by just running it again.

   I check the web log, it contains

   (104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server, referer: http://dreamware.com.hk/ischool/DBR/index.php
   Premature end of script headers: report.php, referer: http://dreamware.com.hk/ischool/DBR/index.php" error

   It doesn't seems to be timeout, as the "500 internal server error" came up so quickly and I've increased the timeout value in fcgid.conf already.

   Please kindly help.

   Thanks a lot

   The "Connection reset by peer: mod_fcgid: error reading data from FastCGI server" error can be caused by several reasons: permission problems, timeout, configuration differencies between web server and FastCGI. As yours happens only from time to time, you might want to check if there are certain reports that cause it (possible timeout for longer running reports) or any reports (possible mismatch in configurations).

   Thanks.
   What are you referring to "possible mismatch in configurations"? Please kindly advise.

   As said, rhe error is such a generic PHP FastCGI configuration error (can be caused by multiple things), so it is impossible to say the cause without access to the server.

   Check which reports will cause the error. If there are only certain ones check the timeout settings. if it happens randomly, there is something else causing it.

   Thanks.But I'm still stuck. I'm still not able to fix this random error. It's not specific to any one of the report, it's very random. if I reload the same report, it can show the result immediately.

   [Mon Jan 12 16:18:24 2015] [warn] [client 218.102.4.205] (104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server, referer: http://dreamware.com.hk/ischool/DBR/index.php?m=4

   Is there any config on DBR I can try?

   Here is the fcgid.conf, I tried to change the number but still can't fix the issue.

   Great thanks for any advices, thank you.

   As this is a PHP configuration issue, you might want to post the question to serverfault.com (or similar site).
