The default on Solaris 7 is 64. Solaris 8 and 9 use 256 with a default  
hard limit of 1024 (65536 on solaris 9).

We have actually fixed this internally, by setting a higher file  
descriptor limit for for the Opera process in the startup script. It has  
been set to 512, which is enough. I'll see if we can do this for Opera 9  
as well. See Bug 227353. (Sorry, internal only)
