Interrupted System Call

Hi there,

I'm using mod_backhand on a 3 machine-webserver-cluster for about 3 weeks now.
On the "Master" I always have this error in our apache-error-log:
[Wed Apr  7 16:50:57 2004] [warn] (4)Interrupted system call: connect() timed 
out

every 2-5 minutes or so, about 100 lines each time.
I've just read about this problem but there was no real solution for this and 
the posts where quite old so I ask again carefully:
Is there a solution or some workaround for this beneath switching keepalive 
off or something?

I already tried to switch off the connectionpool but my apache didn't wanted 
it this way and just hung.
