Hello List!

I have faced the same kind of problem, and nothing seems to help...

Trying to run Grub Next Generation Python Client (http://grub.org/?q=en/node/204) on my FreeDSD 7.1 box with as many
threads as possible. named seems to limit tha number of Grubng threads I can run, because of exessive name service usage of web crawler.

I have recompiled bind with  'CFLAGS+=  -DFD_SETSIZE=4096', but this does not help.

Also, 'sockstat |grep -c named' does now show too big numbers. Namely, around 20 with 60 Grubng threads and around 100 with 100 threads (never exeeding 1500). But with 100 threads 'named' becomes unresponsive.

Messages appear in the log:

named[63198]: socket: too many open file descriptors
last message repeated 26 times

Bind version is: BIND 9.4.2-P2


Any ideas?


Best regards,
O.K.
