Memory Leak happening with Plugin

This is directly from my host regarding this plugin:

If there was a database bottleneck, we would expect to have seen some more database-side utilization instead of that large server-side memory spike; we unfortunately don’t have much information on what in the cron job’s execution was taking up that large amount of memory, but it seems possible there may be something in the cron job’s code causing a memory leak, or perhaps just running the job inefficiently:

This is from our manual run of the cron job, which would not be limited by the site’s maximum PHP memory amount. Checking our cron runner’s logs, we can see that for the automated runs, the cron job seems to hit the site’s maximum PHP memory value, causing a fatal PHP error during the execution of the alg_wc_order_status_rules_<wbr />process_rules job:

This would explain why the cron job does not seem to bring down the server when run automatically, as it gets limited by the maximum PHP memory setting, but may also explain why it takes a long time to run, if it’s this limited by server memory. Raising the PHP memory limit doesn’t seem to be a viable option either, since as we saw from manually running this cron, without a memory limit it would take up all of the server’s memory to run.

At this point, one thing we could suggest would be to get in touch with the plugin’s developer, to double check what’s the expected amount of memory it would take to run this cron job, as the amount used from what we have seen above doesn’t look right. It’s possible that usage could be from a memory leak or similar bug, or perhaps something the developers may have a fix or workaround for, as well.
