Problem description: | |
From the MSGPATH file we can see the servers trying to disconnect: 02:19:13 The SMX connection between high availability servers was closed because the peer server was unresponsive for the timeout period (60 seconds times the number of retries). 02:19:13 The SMX connection between high availability servers was closed because the peer server was unresponsive for the timeout period (60 seconds times the number of retries). 02:19:13 The SMX connection between high availability servers was closed because the peer server was unresponsive for the timeout period (60 seconds times the number of retries). 02:19:14 Error receiving a buffer from RSS rss_server01 - shutting down In the assertion fail file, you will likely only see a partial stack, which is due to the fact that an unexpected error message gets sprintf'd into a local variable that is not large enough to hold it. This corrupts the stack frames and impacts the ability of the stack to unwind. Here's the partial stack: ucontext: 0x0000000114205c40 siginfo: 0x0000000114205f20 si_signo: 10 si_code: 1 si_errno: 0 si_pid: 1668573551 si_uid: 0 si_addr: 0x6374696f6e2073cd si_value: 0x0000000000000000 si_fd: 1668573551 0x101021b40 oninit :: cloneSourceRecvThread + 0xb40 sp=0x237e46b00(0x20696e2074686520, 0x73716c686f737473, 0x2066696c652c2074, 0x68656e2073657474, 0x696e672053365f55, 0x53455f52454d4f54) Following the above MSGPATH output, the server does seem to print an unexpected message into MSGPATH that seems like it's the output for an onconfig parameter description like this: 02:19:14 Error receiving a buffer from RSS rss_server01 - shutting down 02:19:14 Used with the REMOTE_SERVER_CFG configuration parameter, the S6_USE_REMOTE_SERVER_CFG configuration parameter specifies the file used to authenticate secure server connections in an untrusted network environment. The REMOTE_SERVER_CFG configuration parameter is used to specify the name of a file that lists the remote server hosts that are trusted by the computer on which the database server resides. If one or more of the servers specified in the REMOTE_SERVER_CFG file is configured using the connection security option (s=6) in the sqlhosts file, then setting S6_USE_REMOTE_SERVER_CFG to 1 specifies that the servers in the REMOTE_SERVER_CFG are trusted connections. If S6_USE_REMOTE_SERVER_CFG is set to 0, then the $INFORMIXDIR/etc/host.equiv file is used to authenticate servers connecting through a secure port (as defined by setting s=6 in the sqlhost file). 02:19:14 invoke_alarm(): INFO: 1000 bytes in buffer but need 1045 02:19:14 RSS Server rss_server01 - state is now disconnected 02:19:14 Assert Failed: No Exception Handler | |
