Ruby hangs 2.2.4

[zellster]

[Note: This was originally posted under Bugs, but I am curious if any other Ruby users have run into this.]

OS: Solaris 2.8
Arch: SPARC (64/32-bit)
LiteSpeed: 2.2.4 Standard edition
Location: http://206.117.43.99:8088/

I installed 2.2.4 as a non-root user, and added an entry to the Rails template. However, after a day or so of uptime, LSWS no longer accepts connections. The lshttpd processes are still running and don't appear to be hanging:

There are no ruby processes running. I can supply truss output, or access to the admin site.

Thanks!
