Got a problem with a php script on my production environment.
The aim of my script is to read a XML File, parse it and generate new XML records to insert in SOLR. The XML contains many Documents and I loop on the Documents.
Since the last release the script crashed because of memory errors. I log the memory used at the beginning of the loop with get_memory_usage() and I see that it grows regulary.
I don't use static variables, all variables are reassign in the loop. As I read that concatenation might cause memory problem, I use an array and implode after the loop.
Actually my main problem is that the used memory keep stable on my test environment and on the dev one. The scripts are exactly the sames, configuration is the same to (deployed with puppet). Only the hardware is differend (VM on differents clouds). Of course the input files are the sames to.
Do you have any idea of what can cause this difference between my environments? All suggestions that can help accepted, really stucked on this
