Hi.
I notice that sbbs get this error sometimes. I now increase the file-max
from sysctl i will check during this week.but i think that no will solve finnaly the issue.

Maybe sbbs forgot close file desciptors in some place?
I detect this when reading via nntp, and something sbbs cannot open the
areas databases

By default, lsof outputs sockets as well as "files". To just get a list of files, use "lsof /".

I think you're conflating sockets with files. It might be normal for hundreds of TCP sockets to be opened by your NNTP client.

Are sure it's "files" and not "sockets"?

By default, lsof outputs sockets as well as "files". To just get a
list of files, use "lsof /".

when i went researching and digging after reading the initial post, i found a page that basically said to find out what the PID of the program in question is
and then use that on the lsof command line... on max's system i ran the following...


ps -C sbbs -o pid=


which gave me the PID i needed so that now gets fed to lsof...


sudo lsof -p $(ps -C sbbs -o pid=)


which gave me only what the sbbs task was using... from there, one might filter
for lines containing a '/' but that may not be what one wants... in my research, i found a page on lsof for AIX systems that uses "-t type" to list only items of that type... on my ubuntu system, the lines with file names are of type "REG" (regular file) but i don't find a command line option to output only those lines... so grep to the rescue in the end...


sudo lsof -p $(ps -C sbbs -o pid=) | grep -e " REG "


and i have only the open files... i've added the header for clarity of the fields...

sorry for the wrap... there's nine columns ending with the full path and file name...

i notice that node.dab is opened twice... maybe there's something to that with the problem we see on Max's system about not being able to lock it or whatever that error is that we've been seeing?
