Alfresco Share: java.net.SocketException: No buffer space available

Question

I'm using Alfresco 4.0d + MySQL + Win 2008 R2. About once a week in the logs this message appears:

java.net.SocketException: No buffer space available (maximum connections reached?): JVM_Bind

After that, it is impossible to Alfresco Share login. Tried fixpack, which is advised https://issues.alfresco.com/jira/browse/ALF-13666 http://stackoverflow.com/questions/10088363/java-net-socketexception-no-buffer-space-available-maximum-connections-reached Does not help. Please give advice on how to solve the problem. Thanks.

Have you tried switching back to Lucene? I know the 4.0 community & enterprise series aren't fully bug-free with SOLR. Hence I would just try to set the search subsystems to lucene, restart and check it. — Tahir Malik

Its a bug in Windows 2008 R2.

I answered the question in this post: java.net.SocketException: No buffer space available (maximum connections reached?): JVM_Bind

Ah sorry, just noticed you tried that already. Try disabling multithreaded tracking in the solr config files.
