[Glass] Swazoo server hangs

[Johan Brichau]

Hi Otto,

To check if a fastcgi process is up-and-running, you can use monit [1] with the following configuration. I believe I found this online somewhere, perhaps [2].

You will want to adapt the <code to start the seaside gem> part. I just copy/pasted from our configuration and removed that command since we have specific scripts for our setup. I believe it should be something like this: "startSeaside30Adaptor FastCGI 9001".

Here is the part for monit. Just copy/paste it for each fastcgi port you are running.

check process fastcgi_9001 with pidfile /opt/gemstone/product/seaside/data/FastCGI_server-9001.pid
        start program = "<code to start the seaside gem>" as uid sites and gid sites
        stop program = "<code to stop the seaside gem>" as uid sites and gid sites
	# Empty FastCGI request 
	if failed port 9001 
		  # Send FastCGI packet: version 1 (0x01), cmd FCGI_GET_VALUES (0x09) 
		  # padding 8 bytes (0x08), followed by 8xNULLs padding 
		  send "\0x01\0x09\0x00\0x00\0x00\0x00\0x08\0x00\0x00\0x00\0x00\0x00\0x00\0x00\0x00\0x00" 
		  # Expect FastCGI packet: version 1 (0x01), resp FCGI_GET_VALUES_RESULT (0x0A) 
		  expect "\0x01\0x0A" 
		  timeout 10 seconds 
	then restart

Hope this helps!
Johan
