Xen users - Aug 2006 - Weird glibc bug, Process becomes unresponsive. Xen related?

Hello List,

I have a Xen server running as my web server. One of my processes gets 
this in his stderr-log about once a day:

*** glibc detected *** /usr/bin/ruby: free(): invalid next size (fast): 
0x092229b0 ***

or even

*** glibc detected *** /usr/bin/ruby: malloc(): memory corruption: 
0x098535b0 ***

(less frequently).

The process is at that moment in a weird limbo, not reacting to inbound 
tcp connections, but not consuming processor or memory resources, 
sleeping. I can''t kill it, even as root. It says: Permission denied.

I am willing to provide any kind of detail, but first, let me ask this, 
dear fellow hackers: Can this be in any way related to the Xen 
virtualisation layer? Am I even in the right list?

best regards,
