Connection information set in the NUMFDSERVERS configuration parameter

For network connections on UNIX, use the NUMFDSERVERS configuration parameter to specify the maximum number of poll threads to handle network connections migrating between Informix® virtual processors (VPs).

Specifying NUMFDSERVERS information is useful if Informix has a high rate of new connect and disconnect requests or if you find a high amount of contention between network shared file (NSF) locks.
