Same thing happens with Resin 3.0.13 and 2.1.16 on Fedora Core 4. Works fine without the "start" switch. and with it just screws up. |

Changing priority since this is with a new operating system and has been working without modification with several other unix operating system for years. |

We have this problem with Fedora Core 3, and a 'nasty' workaround - I hope this helps:
-An update containing IPv6 was installed on the FC3 server.
-I tried starting resin (both resin-3.0.14 and resin-3.0.12) and got the same result (nothing in the resin stderr or stdout logs, and a java <defunct> process) - and resin just tries restarting over and over.
-I modified wrapper.pl in resin/bin to comment out the following lines (~ line 712 - see bottom of my comment). This sent the error messages back to the console. I've lost the exact error messages, but it was along the lines that "Can't start java:... the child process needs to connect to the parent process, but socket=null". Sorry for not having the exact error msg :(
-The workaround was to remove Ipv6 from the server and it started fine with Ipv4.
resin/bin/wrapper.pl - line 712
if (($child = fork()) == 0) {
close(S);
# close(STDOUT);
# close(STDERR);
# open(STDOUT, ">>$jvm_log");
# open(STDERR, ">&STDOUT");

Commenting out those lines seemed to have resolved the issue. Resin starts out fine with the start switch. Weird, eh. I am going to do some more testing see if i can pin point the problem to what is really causing the problem. I didn't hage the Can't start java error message though.
I'll comment if I find anything. |

I believe I found the cause...
if you run lsmod, you'll see the ipv6 module loaded. It seems to be a pretty low level module with (in my case) 36 dependencies. I renamed the module:
# cd /lib/modules/2.6.12-1.1398_FC4/kernel/net/
# mv mv ipv6.ko ipv6.ko.unused
then rebooted
wrapper.pl worked properly after doing this.
I can't imagine there being an issue with not loading this module.. if anything, less things to be worried about.

A better option is to do this '
echo "alias net-pf-10 off" >> /etc/modprobe.conf
this'll prevent ipv6 module from loading.
This is a better method as the first will be overwritten with th enext kernel upgrade.
I tested this on a freshly installed FC4 box.
