After a few days (under very low load), the exception mentioned in the title starts to network error ioexception: no buffer space available (maximum connections reached?): connect appear in the logs, no new connections can be established from that point on, the only fix is then to reboot the server. Environment: Latest Tomcat 6 Windows Server 2008 R2 JDK 6 update 30 SQL Server 2008 Kerberos authentication Evidence collected so far: netstat shows no excessive amount of connections ProcessExplorer shows no excessive amount of open file handles system main memory usage is average JVM heap usage is average restarting Tomcat does not solve the problem Open questions: if we were leaking connections, shouldn't they show up in netstat? shouldn't a restart of the appserver resolve the problem, because the OS should free all process resources? is there a way to trace the problem to its origin? E.g. installing monitoring software, maybe something similar to lsof etc.? I'm out of ideas, any hints appreciated! windows tomcat jvm socketexception connection-leaks share|improve this question edited Apr 10 '12 at 12:05 asked Apr 10 '12 at 11:58 Michael Böckling 2,22432134 There are lots

This could be caused by another application on the same server as JIRA is leaking sockets (opening lots of sockets, but never closing them). For example, a real time database mirroring. Resolution no buffer space Temporary disable any application or applications' mechanism which might used up a lot of sockets. Run netstat -n on the server hosting JIRA (if Linux) and check whether sockets are being created excessively by applications. Was this helpful? Yes No Thanks for your feedback!

I googled around, and found that this is an issue with the Win 2008 R2 server, Reference Links: http://stackoverflow.com/questions/10088363/java-net-socketexception-no-buffer-space-available-maximum-connections-reached https://support.microsoft.com/en-us/kb/2577795 We are working on implementing the fix and try it again. However, we have seen this error with sonar-pdf-report plugin only. However, I am just highlighting from the part of using HTTP client from the report plugin, as stated in below link, http://stackoverflow.com/questions/6068423/java-net-socketexception-no-buffer-space-available-maximum-connections-reached Stack trace for more information, [INFO] Retrieving measures [INFO] Retrieving most violated rules Dec 22, 2015 1:45:12 PM org.apache.commons.httpclient.HttpMethodDirector executeWithRetry INFO: I/O exception (java.net.SocketException) caught when processing request: No buffer space available (maximum connections reached?): JVM_Bind Dec 22, 2015 1:45:12 PM org.apache.commons.httpclient.HttpMethodDirector executeWithRetry INFO: Retrying request Dec 22, 2015 1:45:12 PM org.apache.commons.httpclient.HttpMethodDirector executeWithRetry INFO: I/O exception (java.net.SocketException) caught when processing request: No buffer space available (maximum connections reached?): JVM_Bind Dec 22, 2015 1:45:12 PM org.apache.commons.httpclient.HttpMethodDirector executeWithRetry INFO: Retrying request Dec 22, 2015 1:45:12 PM org.apache.commons.httpclient.HttpMethodDirector executeWithRetry INFO: I/O exception (java.net.SocketExcepti
