      Hello,

      I've got fresh install of Zabbix Appliance 3.2.3 with restored database from Zabbix version 3.0.7 (zabbix 3.0.7 worked fine with this database).

      Zabbix server starts fine, works for some time (10-60 min) then randomly crashes with following messages in log:

      *** buffer overflow detected ***: /usr/sbin/zabbix_server: unreachable poller #16 [got 0 values in 0.000004 sec, getting values] terminated
      ======= Backtrace: =========
      /lib/x86_64-linux-gnu/libc.so.6(+0x7329f)[0x7f9c4803d29f]
      /lib/x86_64-linux-gnu/libc.so.6(__fortify_fail+0x5c)[0x7f9c480d4bbc]
      /lib/x86_64-linux-gnu/libc.so.6(+0x109a90)[0x7f9c480d3a90]
      

      In zabbix_server.conf there is following setting:
      StartPollersUnreachable=20

      I tried to decrease it to 10 and even 3, but that didn't help.

      I'm attached some log files (zabbix_server-debug4.zip is a log with Debug level 4).
