I'm fairly sure that Java does not provide access to UNIX domain sockets, so this would have to be at the JVM implementation layer. Obviously, Tomcat could be mismanaging some resource which ultimately leaks these things at the native level, but it's not like we can grep the Tomcat code for "new UNIXDomainSocket" or anything like that. > The leak is absent when Tomcat runs using the BIO connector, and > this would indicate a problem in the NIO connector implementation. > > I've seen the same situation indicated by someone else in the past, > but with no response: > http://mail-archives.apache.org/mod_mbox/tomcat-users/201201.mbox/%3CCAJkSUv-DDKTCQ-pD7W=qovmph1dxexovcr+3mcgu05cqpt7...@mail.gmail.com%3E There > certainly was a response: http://markmail.org/message/wvurlmltc4mxtrcp If you can provide more information, I'm sure it will help to diagnose any problem. Are you able to upgrade to the current version of Tomcat 7? - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEAREIAAYFAlFDhS8ACgkQ9CaO5/Lv0PAr8gCgvAAXZkMQetf2UpsxlPfei9BC YesAnjeYavpJsW5cN4sOuj/nowE7ODs/ =5nyS -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
