The Zabbix escalator process appears to be "stuck". I first noticed it from my trigger in Zabbix to see when the escalator process is busy. My escalator process has been 100% busy now for 1 day and 19 hours. By running a "ps" on the command line I can see that the escalator process is basically "stuck". It always looks like this:

zabbix 32195 31650 0 Apr25 ? 00:03:42 /usr/local/zabbix/sbin/zabbix_server: escalator [processed 193 escalations in 26651.404923 sec, processing escalations]

I can run "ps" over and over and it will always return with that exact same result. The CPU time hasn't even changed. The Zabbix server processes otherwise appear healthy. The CPU/memory/disk/etc. all look fine. The database does not appear unhealthy either. There are no stuck queries in the database.
