I’m trying to upgrade from jruby 1.5.1 to 1.6 but I’m seeing some strange errors when using capistrano. The jruby-openssl version is 0.7.2 and the capistrano version is 2.5.21 for both so the only relevant difference seems to be the jruby upgrade. Also, I think this is only a problem when deploying from a mac to linux machines. The problem seems somewhat random as to the specific error and machine. Anybody with some idea of what I could do to resolve this issue? I sure would like to upgrade! Here are some examples: ~\> cap utility cmd=‘echo foo’ - executing `utility’ - executing “echo foo” servers: [“web1”, “web2”, “web3”, “web4”, “web5”, “web6”, “db1”, “db2”, “db3”, “db4”, “app1”, “app2”, “app3”, “app4”, “app5”, “app6”, “app7”, “app8”, “app9”, “app10”, “msg1”, “msg2”, “ftp”] connection failed for: msg2 (Net::SSH::HostKeyMismatch: fingerprint … does not match for “msg2”), app1 (OpenSSL::Cipher::CipherError: Input length not multiple of 16 bytes), app8 (OpenSSL::Cipher::CipherError: Input length not multiple of 16 bytes), app10 (OpenSSL::Cipher::CipherError: Input length not multiple of 16 bytes) ~\> cap utility cmd=‘echo foo’ - executing `utility’ - executing “echo foo” servers: [“web1”, “web2”, “web3”, “web4”, “web5”, “web6”, “db1”, “db2”, “db3”, “db4”, “app1”, “app2”, “app3”, “app4”, “app5”, “app6”, “app7”, “app8”, “app9”, “app10”, “msg1”, “msg2”, “ftp”] connection failed for: db2 (Net::SSH::Disconnect: disconnected: Packet corrupt (2)), app5 (Net::SSH::Disconnect: connection closed by remote host), web1 (OpenSSL::Cipher::CipherError: Input length not multiple of 16 bytes) ~\> cap utility cmd=‘echo foo’ - executing `utility’ - executing “echo foo” servers: [“web1”, “web2”, “web3”, “web4”, “web5”, “web6”, “db1”, “db2”, “db3”, “db4”, “app1”, “app2”, “app3”, “app4”, “app5”, “app6”, “app7”, “app8”, “app9”, “app10”, “msg1”, “msg2”, “ftp”] connection failed for: app2 (Net::SSH::Disconnect: disconnected: Packet corrupt (2)), msg2 (Net::SSH::HostKeyMismatch: fingerprint … does not match for “msg2”), app5 (OpenSSL::Cipher::CipherError: Input length not multiple of 16 bytes), ftp (OpenSSL::Cipher::CipherError: Input length not multiple of 16 bytes), app3 (OpenSSL::Cipher::CipherError: Input length not multiple of 16 bytes) ~\> cap utility cmd=‘echo foo’ - executing `utility’ - executing “echo foo” servers: [“web1”, “web2”, “web3”, “web4”, “web5”, “web6”, “db1”, “db2”, “db3”, “db4”, “app1”, “app2”, “app3”, “app4”, “app5”, “app6”, “app7”, “app8”, “app9”, “app10”, “msg1”, “msg2”, “ftp”] connection failed for: ftp (Net::SSH::Disconnect: connection closed by remote host), app7 (Net::SSH::Disconnect: connection closed by remote host)
