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.
