In these cases, the only option the server has is to close the connection and then let the TCP stack purge the connection after some time in the penalty box (FIN_WAIT, FIN_WAIT2, or TIME_WAIT). If you see these kinds of connections piling-up, you may want to tweak the options of your TCP stack to have them cleared-out more quickly. - -chris -----BEGIN PGP SIGNATURE----- Comment: Using GnuPG with Thunderbird - https://www.enigmail.net/ iQIzBAEBCAAdFiEEMmKgYcQvxMe7tcJcHPApP6U8pFgFAluzrmsACgkQHPApP6U8 pFh2rg//cX7UAqis6qKHTDpgOSSBjFIusm7kdxW58/VpWcp/JzUfNhFLLl0aeCsT NbU38l0W0UqYXTCu0sMuPCKGLGYpwuAOCuWq6mJq4VFWtUCyBmCP/A2pvtTzW8js f4e0npXpp/3TxdDx9xNpLfWDv6nzqyzEXhIvfWvjtxNmcA1kGq2ueeHgVCWwb6v0 CJ1VbF52R3B8Gq61u86uV8PPTsUKVIDnn+e+snkLlGMl+lcdBUcGBsxguOaoDHca lRN4gkpXjk946Nor7wPkMG4hUBndD7L/nhWNqrqZnd8TKJJxD+98U419LRFq0xSG qyAx75oNUUwo2l14q/xGTdAGwOzijfOyvnVscljV9fWGEtOMjOFoqPFlHK6QCec7 ysZGuSoEJPuBYfFzdnQE4aOiRNYnAkYAmv6CEq/o0DEgZpuxm/ZAaMzrfP6XH8wk 072o62Cq0gN50q2KYSi7XJD61Akh4nJUl/7XSYKFU8Tj+jHYQBdw22EXEsgrhPuW gyTdH4TxHv40NmMOv9YQXOA0oyiXq/PXGA85gIhQyJdFoa4U8LXC++UBJCk3gNW8 pOO2pFSJ8WAfOrK45Fcl/NgK4066BSqaQu6txnb/Bo/7VCPrPZvZ2/VgLaO/L6jD nb8sXBkozGtrS2sigKHx7HzJNb0r5EE1Uqbpk3YFYcntrl4afHs= =yRjT -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
