  • 1.  BlockLogXmit status

    Posted 01/08/26 01:39 AM

    Dear All,

          Happy New Year to All.

                    I'm working on Informix 14 on Solaris 5.

    We get one issue mostly in every 3 months around for replication issue between Primary Server and RSS server and get the status on Primary server as "BlockLogXmit" and we need to restart the RSS node, and it impact the application connected with the RSS node.

    How can we avoid these situation? in 2025 we faced this situation around 4 times. Kindly suggest.

    Thanks

    Amit Patel

    Hi

     

    Which release of 14 are you running? We use 14.10.FC11 and see this issue with some of our installations. I assumed it was fixed in FC12 but can't find an exact match in the release notes.

    As already stated by Marcus, this is a known defect that is fixed from 14.10.FC11 onwards.

    Besides the bug fixes, there were important performance enhancements to RSS in later releases. Upgrade!

    Amit and Stuart,

    This support article doesn't mention that this issue doesn't happen randomly. It happens when the number of reads (or possibly writes) on the RSS shown by 'onstat -g smx ses' reaches 4,294,967,296 (2^32). 'onstat -z' won't help here. Therefore you will only see this on busier systems and at fairly regular intervals in time, dependent on activity. Knowing this you can monitor it and schedule a restart at a more convenient time.

    Ben.
