503 Service unavailable (mongrel + xampp)
Added by Pablo Bleyer over 14 years ago
Hi.
I am having problems with my Redmine installation on a Windows machine running xampp. Apache talks to mongrel via mod_fcgid. Everything was perfectly, however if mongrel is inactive for a while, I get a 503 error through Apache opening the Redmine page. After a minute or so, the connection works again and stays like that till other period of inactivity.
I have trying modifying the MySQL timeout but I don't think this is the source of the problem. My Apache error logs look like this:
[Tue Feb 23 09:34:43 2010] [error] [client 192.168.65.146] (OS 10054)An existing connection was forcibly closed by the remote host. : proxy: error reading status line from remote server localhost
[Tue Feb 23 09:34:44 2010] [error] (OS 10061)No connection could be made because the target machine actively refused it. : proxy: HTTP: attempt to connect to 127.0.0.1:3000 (localhost) failed
[Tue Feb 23 09:34:44 2010] [error] ap_proxy_connect_backend disabling worker for (localhost)
Does somebody have a clue?
Thanks. Regards.

BTW, I just looked at the Mongrel logs and I can see that I am getting segfaults:

Hello Zachary.
I updated to 0.9.3 and used the Mysql DLL pointed to in the installation guide [http://instantrails.rubyforge.org/svn/trunk/InstantRails-win/InstantRails/mysql/bin/libmySQL.dll]. No crashes so far; keeping my fingers crossed.
Regards.

Hello,
I was experiencing the same problems. I'm using MySQL 5.x, and putting the above mentioned dll in the ruby\bin directory seems to have fixed the problem.
