Q about named not responding the TCP queries

We had a problem where named 9.3.5-P1 running on a Solaris8 box stopped responding to TCP queries while still responding to UDP queries. There was still a listener on TCP port 53. It took a stop/start of named to correct the issue.
At the time that this event occurred we saw this in the messages file:
Nov 20 13:35:31 ... named: [ID 873579 daemon.error] internal_accept: fcntl() failed: Too many open files
Has anyone encountered this situation before? What was the cause? What was there a fix/workaround other than updating BIND? Is this an issue with the underlying OS? Just increase ulimit?
Searching on the web didn't get results dealing with this particular situation.
