Bind bind-9.3.6-16.P1.el5_7.1 - socket.c:4373: unexpected error

[Rafał Radecki]

Hi all.

Today we have had a problem with bind on our server. The server
stopped responding queries and we had to restart the service.
In logfile there was:

Feb 27 13:44:13 dns1 named[21599]: isc_socket_create: fcntl/reserved:
Too many open files
Feb 27 13:49:18 dns1 named[21599]: socket.c:4373: unexpected error:
Feb 27 13:49:18 dns1 named[21599]: 22/Invalid argument

Linux dns1 2.6.18-238.9.1.el5.028stab089.1ent #1 SMP Thu Apr 14
14:41:35 MSD 2011 i686 i686 i386 GNU/Linux

I haven't found anythig useful about this error. What should be done
with such a bug? Have you seen such a bug and can you give some info
about it?

Best regards,
Rafal Radecki.
