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:

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.
