If, as Suvendu suggests, you take more than one thread-dump in a row -- maybe 10 seconds between dumps -- and compare them, you can detect whether or not those threads just happen to be waiting one time, or if they are waiting forever. > ODBC on the actual Window machine hosting Tomcat is Oracle in > OraClient11g_home1 (we have a 12c Oracle database) with a pool > timeout set to 60.

You can probably discover a lot from thread dumps without changing anything. - -chris -----BEGIN PGP SIGNATURE----- Comment: Using GnuPG with Thunderbird - https://www.enigmail.net/ iQIzBAEBCAAdFiEEMmKgYcQvxMe7tcJcHPApP6U8pFgFAluurbsACgkQHPApP6U8 pFgf/BAAkI/Bqy/mqcguHVaZYY1x3dOmIsGoVvIo2jKi6PUqQOdsPCwb1FR97Eoq jtyuAiOk9bUnDUDE6l/1fNV8e2z6QHrVCGWog+3sjejpJGv4Dkfslm+wW1PsQU+/ fsd3ihtWRSyAqSNhfKuVB394yBubKuVqvHGYK6rRjyRMZ/b6JAEGOEW6/B3QBUV/ bB3TfYPZ1ih6lBrCIHaHYlFwwcVIVqqT7YJkAurdYdopqke9WY+fkgNO3i855zmV yujcHPMjC8Y7PW9rw5VOlevYBsuxS3jf/62iXyj4fSbhUzpxrRAk0qc/dukzioFF rgXs9VY3sJBvcmGt9bLfMiPwB9l52a/lloIiNYhitZ6ASaEKYAQqukpBwqL86NuC 8aSUNAzCt80Tr1DZZLP46KnzCfHDWocobF42locqHhe3iJ7PahfsQVVKYJ1cwyga 70qy+oBf3fzBTWq2LrA+a3TaOyOO7SVSY+NmKMS+7FNiicR18ace50PAHzjBN5eB hOCaqeMdJh05Ip7u95VjBUqxlnc+fNli7D1rRy/jXOO/T3eqWg5nMUyrGxSVxomx C4CU6hrc44dQeSZg2jXkgzlKOLGPmeOO+T8nPZ26Mdg2dlbbuSvSE0mydJvZzAao Y1xmLJJDe6ciMYMkSP3JKC1bjylrRhZAZ+MC4C2iJKY564/mWQQ= =uG5n -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
