zfs/nfs/proftpd problem

[Daniel Braniss]

after upgrading the 'ftp storage' from 8.3 to 9.1-stable, our ftp
server is stuck.

the old, (ProFTPD Version 1.3.2) and working till before the upgrade is stuck 
in nlmrcv:
...
10000  1213   992   0  44  0  7340  3692 nlmrcv D     ??    0:08.07 proftpd: 
ftp -
	crawl-66-249-73-193.googlebot.com: anonymous/googlebot at google.com:
	   RETR 00690145.JPG (proftpd)
...

so we upgraded the ftp server too, to 9.1/ProFTPD Version 1.3.4b and this one 
is stuck in rpccwnd:
10000 1197  984   0  20  0  32292  4792 rpccwnd  D    ??  0:00.01 proftpd: ftp 
-
        mbpro.cs.huji.ac.il: anonymous/mozilla at example.com: LIST (proftpd)


any wise suggestions :-)

cheers,
