6 years ago I got a similar issue: "View History For This Host" in Thruk with a larger time frame crashes Naemon. 1 week was enough for a server with many changes in the logfile. The largest json result without crash was 14855 bytes in size.
When the "Sort:" line is removed from the query it works.
Naemon generates a segmentation fault here: https://github.com/naemon/naemon-livestatus/blob/16d932d47acc3d832c7c639b1daea85f0a507b0b/src/Query.cc#L1232
The pointer address "0x6d6f5a006e616c2e" is a part of the query answer: ".lan\x00Zom"
naemon-core 1.0.8 naemon-livestatus 1.0.8 thruk 2.22

After upgrading from naemon 1.0.7 and Thruk 2.19 (long overdue upgrade on my part), the naemon process would terminate with a SIGABRT when access status information from Thruk. Some sections would display the information as expected while others would report "connection refused" for the livestatus socket (obviously due to the crash above). Tracked the issue down to when livestatus is sent a query containing a sort option. Capture the query sent just before the crash, removing the sort options and sending it again (unixcat to the livestatus socket) resulted in data being returned, adding the sort options back in resulted in a backend process crash. Not sure if this is a livestatus or naemon-core issue.
Current versions
Naemon = 1.0.8 Thruk = 2.22
Query that causes crash (not just limited to this one, any with sort seem to be an issue)

Same query without the sort(s) work fine.
