[Xapian-discuss] xapian-tcpsrv php in real fastcgi loop

[Martin Regner]

Ok, thank you very much. I try the two instances as a more stable variant. 

Secons step is to check 1.1.0 (have to make shure that build on our Suse based 
live system).

How stable is xapian-1.1.0? Are there big issues i should know of?

Thank you again for the quick reply. I love open source.

Greetings DonMartio
