We are trying to attack this problem from multiple avenues, thus I'm 
starting a separate thread.  This is with regard to the problem posted 
via thread:

One thing we are seeing with this move to the new hardware (and rhas 4) 
is database connection processes that are left over by users who have 
exited the application.  I've attached to these processes via gdb and 
find they all have the same backtrace.  Any insights into what might be 
causing this issue would be appreciated.  Understand, we did not have 
this problem on the previous hardware running on rhes 3.  Here is the 

#0  0x00ba47a2 in _dl_sysinfo_int80 () from /lib/
#1  0x0019f1de in __lll_mutex_lock_wait () from /lib/tls/

#8  0x00bec527 in exit () from /lib/tls/
#9  0x0816a52f in proc_exit ()

Until later, Geoffrey
