So.... I'm playing around with Amazon's Elastic Cloud and I'm having trouble getting Courier-Authlib to run. I've turned DEBUG to "2" and found the following:

[root@ec2mail001 mail]# /etc/init.d/courier-authlib start Dec 26 21:25:41 ec2mail001 authdaemond: modules="authmysql", daemons=5 Dec 26 21:25:41 ec2mail001 authdaemond: Installing libauthmysql

Looks good right? Well, if I do a process list I find that it's not running. How do I troubleshoot this? I did notice the following:

[root@ec2mail001 mail]# /usr/libexec/courier-authlib/authdaemond INFO: modules="authmysql", daemons=5 INFO: Installing libauthmysql Floating point exception

I did an strace here and found this:

open("/usr/lib/libidn.so.11", O_RDONLY) = 5 read(5, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0\3\0\1\0\0\0\0M,H4\0"..., 512) = 512 fstat64(5, {st_mode=S_IFREG|0755, st_size=193764, ...}) = 0 old_mmap(0x482c3000, 195264, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 5, 0) = 0xb7e10000 old_mmap(0xb7e3e000, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 5, 0x2d000) = 0xb7e3e000 close(5) = 0 --- SIGFPE (Floating point exception) @ 0 (0) ---

Any ideas? This was installed via an RPM that was built directly on the EC2 server.
