[Samba] panic: Unable to open new log file ... Too many open files

Wed Aug 15 16:03:38 GMT 2007

Hi,

debian etch + samba 3.0.24-6 on 2.6.18-4-amd64.

Today I got a panic email from samba.

I found this "Too many open files" message only in one users logfile. Is this
something to worry about or maybe a client problem?
