Do you mean

each biggest-FD instead of comparing with max())

Do you mean you've patched the source code, and if so, how do I get that
patch? Do I have to move from the stable trunk?

you will get that message from that worker while the others run fine with

The first log occurences are:
2013/07/23 08:26:13 kid2| Attempt to open socket for EUI retrieval failed:
(24) Too many open files
2013/07/23 08:26:13 kid2| comm_open: socket failure: (24) Too many open

2013/07/23 08:26:13 kid2| WARNING! Your cache is running out of
filedescriptors

Then later:
2013/07/23 10:00:11 kid2| WARNING! Your cache is running out of
filedescriptors
2013/07/23 10:00:27 kid2| WARNING! Your cache is running out of
filedescriptors

After that, the errors become prolific

Thanks for the help.
