sockets error?

Has anybody seen this before? We had this problem today on your hpux N9000 11.00 server running 7.31FC4 .... we finally rebooted 13:57:07 (3915) sockets error - registering a file 13:57:07 listener-thread: err = 0: oserr = 0: errstr = : 13:57:07 (3916) sockets error - registering a file 13:57:07 listener-thread: err = 0: oserr = 0: errstr = : 13:57:08 (3918) sockets error - registering a file 13:57:08 listener-thread: err = 0: oserr = 0: errstr = : 13:57:08 (3919) sockets error - registering a file 13:57:08 listener-thread: err = 0: oserr = 0: errstr = : 13:57:09 (3921) sockets error - registering a file 13:57:09 listener-thread: err = 0: oserr = 0: errstr = : repeated upteen zillion times until we rebooted informix tech support suggests that some kernel parameter changed.
