Very high memory usage on bulk insert of documents about solr-php-client HOT 5 CLOSED

I was able to quickly verify what you report. Seems very unfortunate to me that 
there is no way to free the 
memory from the stream context resource. Using a new context seemed cleaner 
code wise, but its obviously not 
acceptable. I'll move to reusing a single context.

Moved to reusing a get and post context instead of creating a new one for each 
request in r21

further fix in r22 (wrong stream context function used to set options)

I am having a rather large performance issue which I think is related to this.  
I am using the newest code however I think this is leaking.  I am trying to 
index between 6 and 10 million documents and even with a memory limit on php of 
4 G, I get to maybe 1 million before it eats up the memory.  I have tried doing 
this in chunks of 100,000, 10,000, and 1,000 and it all just dies and seems to 
be around this function.

Thoughts?  better approaches?

Are you using the SVN version of the code? it now reuses a context. If you are 
and are still seeing memory climb - then I'd check whether you're holding onto 
documents somewhere. If that still doesn't work, then you could try breaking 
the work into several processes.
