We are running 7.0.57 in production and all seems well with the AjpNioProtocol. The same configuration with maxPacketSize="65536" in development fails with the above problem, but with the default packet size (8192), we see no problems. I'll try some other packet sizes to see if this is just a problem with 65536. Perhaps 2^16 is a particularly problematic buffer size. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 Comment: GPGTools - http://gpgtools.org iQIcBAEBCAAGBQJU7eqvAAoJEBzwKT+lPKRYyjkP/0cIJyGSD8eMNilSRbYCqVa0 RmkGeTRK0rywEaZPkahIjCOBo5VMfOMTrugHiZu9i0p68K7VUynfeONi20hcyAnJ J1qxCDZskgWhQtoajEvXm5oGaeZ5TyCJUNKRa31ygnuR5EqN1PRt8VF221eMhEqN nPqQtz4DRtQcnk9wyPMNOFAdDkVRhzIiIyhwiG7Cu9AMpZdAHwHcKhwLVJnapFrm MjN0AiVLF3q4JAdBoyswjGM7nJthqxaI4Ux8zOusLeFDbIoy6IK1+y9ZlcIcWz6r S9yEz6qJS5mLuAq1iSeq3uLUwISPTMJfXONGnU6uUyFbHac9EcjLMQSJQEfwyjAB Z/v/v43gTa4sif3K7omWiqhAOstXBbIjGVxKHWH2lgkBM0AnslqMYdapQ6Q8Unfl r9Pe1ScV+zAWQp+krBpJ3qXmkbQGuOIV49sCpjFJD6s1f4SajxueryaogvJzRLcy BfgRkxsBDrjbsfEPjHHDi7w2o81Mvh/PToH1HLw8QysftZhcg2qJrX4YP6+XER7N xt4Z5bhniI4BAMLjNjleIDCzJRy+WmoIOYZEOlzarywguIFxg2BjNb794RfV4f4v 2VS7IBjyWsozyM8zmluTD2jrCHok5ESyil+FAH+uQSplX6IfGqpCe3Z9bW4qSxZ4 y7Ta7oEojJ9OYyCc4gZF =Vgsx -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
