Subject: Re: [MTT users] Can not find my testing results in OMPI MTT DB
From: Ethan Mallove (ethan.mallove_at_[hidden])

I see a bunch of these errors in the httpd logs today:

  PHP Fatal error: Allowed memory size of 33554432

Could you send your INI file? One way around this issue is
to submit fewer test results at one time by breaking up your
large MTT run into multiple runs. If you're running on the
trunk, this parameter will submit results after each run.
