  • 1.  2Gb limit on universe.log size with $Universe v5.33

    Posted Dec 13, 2019 10:08 AM
    Hello all,

    We realized yesterday that there seem to be a 2Gb size limit on universe.log file in $Universe v5.3*
    Once that file reaches 2Gb, the company will shut and will not restart. 

    We also noticed this morning that the online reorganization was generating a huge volume of logs, and was causing the universe.log file to reach that limit very fast

    Reading the universe.log, it looks like the uxreorg command was trying to run several buffer address modifications over and over again without being able to complete them

    Between 09:00am and 09:45 time at which the node crashed, more than 14 million such lines were written in universe.log

    Has anyone ever had such trouble ?
    Thanks in advance for your feedback,

    Regards,

    Toni

    You can handle universe logs by setting a limit then once the log reaches this sixe another one is created and the old one can be archived. The usual limit is the size of the memory.

    It is difficult to actually open  log of this size so how useful is it for troubleshooting.

    Even for older versions of $U it is worthwhile upgrading to last release 5.6 with patch FX24520 as the reorg is better. 

    Obviously going to v 6 is ideal but there may be good reasons to stay on 5.

    You did not mention what architecture this is node is on, Windows or Unix/Linux.
