A single, multi-thread application?
There is another limit built into the kernel for applications that use 'select'
to get notifications of connection attempts to file descriptors.
That limit is the hardcoded size of the file descriptor select structure (in bits).
Not sure off-hand how big it is, I think either 64 or 128 bits (open descriptors
monitored).
You might have to run multiple instances of the e-mail application if this is the
cause of the error message.
