[JBoss JIRA] Created: (JGRP-556) Consolidate thread pools

Consolidate thread pools
------------------------
Key: JGRP-556
URL: http://jira.jboss.com/jira/browse/JGRP-556
Project: JGroups
Issue Type: Task
Reporter: Vladimir Blagojevic
Assigned To: Bela Ban
Fix For: 2.6
For JGroups 2.5 we have used numerous instances of ThreadPoolExecutor(s) as we needed them. For instance, STREAMING_STATE_TRANSFER, Multiplexer, TP, and ProtocolStack. Undoubtedly this lead to increased overhead and performance impact that we have not measured. First of all we should stop indiscriminately introducing new thread pools as we go further. Second, we should Investigate possibility to consolidate thread pools so they can be reused by various protocols and components of a channel.

[JBoss JIRA] Created: (JBPORTAL-1782) CMS security checks using ldap causes "too many open files" error

CMS security checks using ldap causes "too many open files" error
-----------------------------------------------------------------
Key: JBPORTAL-1782
URL: http://jira.jboss.com/jira/browse/JBPORTAL-1782
Project: JBoss Portal
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: Portal CMS, Portal Identity
Affects Versions: 2.6.1 Final
Environment: Linux
Reporter: frontline frontline
Assigned To: Sohil Shah
I have configured the portal to use OpenDS as the "user store".
I noticed that if I log in as some other user than admin and then perform many CMS operations I eventually get an "java.net.SocketException: Too many open files" error.
Apparently the portal always opens a new connection when getting role info etc. for authorization? So there is no caching or even pooling of the ldap connections? Isn't this also potentially bad for performance (and for the poor ldap server)?
If I wait a while the connections become usable again so there is no connection leak (the sockets are in TIME_WAIT for a while).
Here is the error:
java.net.SocketException: Too many open files
