To reproduce: We don't yet know if the statements finished and just didn't log, or if they didn't finish properly. |

The statements finish properly and syslog is called to log the End SQL debug log line. For some reason, it never gets into the file. The probability is that the test is spewing more log lines than syslog can handle. a quote from somebody's blog: by default syslog willl use UDP to transmit the messages, so an overloaded log server will simply result in the messages being dropped. Sometimes we see poorly formed messages in the debug log due to partial dropping of the text. |
