Name

NETS-101 — Too many file descriptors are requested

Severity

W (warning)

Message text

Required number of sockets (%d) higher than %s (%d)

Description

Function selalloc() was called to prepare select control block but the number of file descriptors requested (the first parenthesis) is higher that the maximum allowed (the second one). The limit should be

  • process file descriptor table size

  • system select array size (FD_SETSIZE).

The function decreases the number of file descriptor to the allowed maximum and continues.

Applications typically allocate this table with some reserved space, so little overlap will probably cause no problem. If the requested number is too high, the application should shortly come into troubles with creating new file descriptors.
