Subject RE: [users@httpd] What is the best way to handle "too many open files" errors?
Date Thu, 21 May 2009 08:23:10 GMT
Hi,

Just to throw a slight spanner in the works here. My understanding of
'open files' is open file descriptors. As far as a file descriptor is
concerned there is no real difference between a physical file on disk
and a socket (network connection). So eliminating physical files, whilst
it might get you a little more headroom, is unlikely to solve the
problem.

I would look at the Apache configuration to see how many connections
your server is configured to handle and compare that to the max files
value from ulimit. I suspect that this is your issue.

Remember that as you add connectivity to databases that this will
increase the number of sockets, and therefore open files, used for each
page served.

Mick

Sean --

Thanks for the lengthy and thoughtful response. 

What I've found most successful so far is hunting through the lsof |
grep
http and finding ways to eliminate unnecessary files. And I'm also
exploring
an expansion of my production resources to include a second tier machine
that houses the database. 

If either of these ideas are stupid -- or there's something more
efficient
-- I'd really appreciate the pointers. 

Thank you.

Ben.
