slapd[26189]: warning: cannot open /etc/hosts.allow: Too many open files

Hello,

today a client to connect via ftp to our server ( SLES 9 ) and I got this error:

slapd[26189]: warning: cannot open /etc/hosts.allow: Too many open files

according to lsof | grep REG | wc -l i have only 3267 regular files open and 4684 counting the IP connections too.

cat /proc/sys/fs/file-nr returns 3573 1185 131072

and file-max 131072 ( as above )

According to this numbers there sould not be a system wide problem.

Is there a limit of open files in slapd ?

I restarted slapd and now it seems to work.

Probably you need to know the version. Can anyone tell me how I get the running version ? There are no entries in /var/log/messages

Thanks Andreas
