Information: Unable to fetch the log file. It could be that it is too big

Mon, 26 Jan 2026 18:19:17 GMT

Hi Guys,

I get this msg:

-----------------------------------------------------------------------

Information: Unable to fetch the log file. It could be that it is too big; try decrease the 'MaxLogRecords' application configuration value (its current value is 1000)"

-----------------------------------------------------------------------

I understand that it means that it returns the first 1000 lines of text from each log file when i access Task Details in QMC. We have quite a big number of apps running that generate hundreds of log files. Its the first time we encounter this. I manually edited to Manegement Service config file and changed the value from 1000 to only 50 (even 100 was too much) but now we run into the issue that we have a big number of lines in each log file that cannot be retrieved from QMC.

Please help me out to figure out how I can remedy this and still show the necessary number of lines for each log file.

Thanks

Hi Victor,

What version are you running?

This should work fine, perhaps you can attach a sample TaskLog that we can try to reproduce with.

Regards,

Erik

Sometimes the error can be misleading. The cause can be determined by temporarily changing the logging in the QMC to DEBUG. This will generate more information in the QMS log which can usually be found here:

C:\ProgramData\QlikTech\ManagementService\Log

Make sure to turn off DEBUG level logging afterwards as the log file size will be considerably larger due to the amount of additional information being recorded.

I hope this helps.
