Close Idle Connections after a certain timeframe has passed too prevent "Too many open files"
error
---------------------------------------------------------------------------------------------------

                 Key: DIRSERVER-1620
                 URL: https://issues.apache.org/jira/browse/DIRSERVER-1620
             Project: Directory ApacheDS
          Issue Type: Bug
          Components: ldap
    Affects Versions: 1.5.7
         Environment: Unix
            Reporter: Steve


Regarding the following post 

http://mail-archives.apache.org/mod_mbox/directory-users/201102.mbox/%3c4D668DED.6020707@gmail.com%3e

ApacheDS keeps connections open (im not certain its just idle connections, there might be
another issue). After a while the number of open connections will exceed the OS default setting
(Too many open files).
The default is mostly 1024 and can be increased - but it should not be necessary when you
have less clients/users than that.

I have a user base with 500 outlook clients - after a while the Too many open files error
occurs. Using netstat i filtered the LDAP connections and saw that they increased per client
IP each day (not all) - some had up to 5-10 connections per IP, in total there where however
only 100 client IPs.

I suggest that ApacheDS automatically cleans up idle or open connections after a while (timer
task maybe?), it should also be aware of the current amount of open connections - in case
a threshold is reached it should start cleaning up connections sooner.
