insufficient system memory to run Log backup !

  • Hi,

    We have a critical production SQL 2000 server where the transaction logs are backed up every hr

    We have made the decision that this needs to be every 30 mins.

    i have changed the maintenance plan to reflect this but now When I run this it fails with insufficient system memory.

    I am not even able to backup the model Log file.

    Yes I can backup any other file except for logs, doesnt make sence.

    I have deleted the plan and created a new one but still same.

    Have tried with just t-sql but again the same message.

    There is plenty of memory 4Gig and ntohing is running that shouldnt be.

    I do not want to take the server down for a reboot unless this is a last resort.

    this is the error log.

  • I am just confused with the error message insufficiant memory and your sollution (you increased the log file space)

  • What was happening? Well everytime i tried to backup the log file manually, using t-sql or starting a agent job I would get this error message.

    My good mate google thrown up some posts with the same error message.

    One I found was here http://www.tek-tips.com/viewthread.cfm?qid=1257380&page=1

    The log files did not need increasing, but hey anything is worth a trying.

    I gave the payments log and extra 50mb and the systems model log an extra 5mb.

    Tried again backing up and they worked.

    strange i know, I was all set for a reboot but thankfully avoided.
