Reply To: Memory Leaks

[Jonathan Moore]

Update: after applying fixes to various possible memory issues, including your suggestion on clearing the wrappers array, I can now consistently produce maximum execution time exceeded rather than out of memory,
disabling WJECF_AutoCoupon fixes the problem,
Turning it back on starts it again.

When I turned the feature on, I tested it and it was working fine, the errors didn’t start until over an hour later but were then regular.

This makes me suspect interaction with the abandoned shopping cart – after an hour my test cart would be counted as abandoned and the abandoned carts would then be tracking them on a cron job.

The actual timeout errors hit common function calls that are too frequently called to be easily traced.
