Hello

I have a problem with naemon when I search in the "history section" in "Previous day" button.

[sni]

so the error only occurs on certain pages? Can you nail it down to a smaller time range?

[dirtyren]

I had the same problem that We fixed with this patch, remember @sni
naemon/naemon-livestatus#29
In our case it happened while querying the table logs.

[andresinostroza1]

I have test this section with a lot of dates and it works.
Naemon crashes within this two dates.

I will try the patch of dirtyren...I will tell you if it works.

[andresinostroza1]

I fixed it with the patch and it works ok!
Thank you very much :)
