But you're using CherryPy, aren't you? And as Tim Golden pointed out,  
you're probably using another 3rd party lib to talk to Sybase. ISTR  
that CherryPy is written in pure Python but if you have a database  
adapter lib it probably isn't.

That's more of a Solaris question than a Python one, and I don't know  
much about Solaris. Is there a system log where Solaris records when &  
why it has killed errant processes?
