Nothing happens when adding items to large numbers of hosts/templates

[heaje]

I just wanted to put this in here as a help if anyone else runs into this issue.....

I had a problem where if I edited/added/deleted items/triggers to a template that modified a significant number of hosts (read 200+), then nothing would happen. After submitting the change, a new page would load, but then would suddenly stop and the only thing that would show on the page was the header.

I found the problem by changing "display_errors = On" in php.ini and reloading apache. The issue was that the memory_limit value for php had been exceeded (although it was set to the recommended value of 128M). I doubled it to 256M and restarted Apache httpd. After doing that, my problem went away.

I've never come across that, and I've always had a 256 memory limit. My site is moderate with 800 hosts monitored and tweaked to just under 200 values per second.

For anyone who finds this later, I ended up realizing was my own fault. I had "debug" turned on for my user, so it was generating a ton of debug data for all requests. that caused PHP to go over the memory limit.
