THOLD Tab Freezes Server After Upgrade

[User1234]

First off, thanks for Cacti, CactiEZ, THold, and all the great work you guys do.

I just upgraded from Cacti 0.8.7c to 8.8a using the CactiEZ 0.7 CD (technically it was a new install and then imported old files, as old Cacti was 32-bit and new EZ CD required 64-bit), but every time I click the THOLD tab, the page freezes up and I have restart SQL (service mysqld restart) to use anything in Cacti. I can also see that it pretty much maxes the CPU.

The out-of-the-box CactiEZ 0.7 version of THold works, but the problem starts after I import the 0.8.7c SQL db. (I was following http://forums.cacti.net/viewtopic.php?f=5&t=48682 for upgrade steps.)

I can still click Thresholds under Management and create a new Threshold.

I've tried disabling it, and removing and reinstalling it under Plugin Management. It's probably something in thold_graph.php, but I'm not sure where to look. I also tried changing the memory_limit in php.ini from 128 to 256, but that didn't seem to matter.

Running on a VM in an ESX cluster fwiw.

Thanks.

Just uninstalled v 5.0 and reinstalled with 4.9 and it's working.
