Oracle Internet Directory (OID) server refuses connections, in versions 9.0.4 through 11g.

oidldapd01s.log shows a lot of errors like:

* ServerListener:2 * ERROR : ServerListener : Max numbers of connections reached. Num Conns = 900, Max Conns = 900, Closing the connection.

Or for version 11g and above logs show:

... ServerListener : Exceeding maximum number of connections allowed. Num Conns = 1024, Max Conns = 1024, Closing the connection.

or

netstat -a | grep port <OID server port> | wc -l shows a steadily increasing number of connections (note that if the OID server and the clients are on the same system then the count will be double the number of client connections).

At the time of the problem ldapbinds may not do not respond.

For version 10.1.2.0.2 and above OID debug level 67108864, "Connection Statistics Dump" will show which application is opening connections in the OID logs.
