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

[Martin Regner]

Hello again,

i've gone a little bit further by reseting the database objects every loop.
But i still got randomly lock exceptions and netstat gives me connections in 
CLOSE_WAIT forever. After lighty restart they are gone.

Is there any way to force a close on the connection?

Greetings again
DonMartio
