Has anyone seen this error when working with a PHP application "out of dynamic memory in yy_create_buffer()"?
The error message that appears in the php error log is: Fatal error: out of dynamic memory in yy_create_buffer() in Unknown on line 0
I have not been able to identify a reproducible case. Increasing memory_limit has no affect on the issue.
"yy_" is generally a prefix for methods created by the yacc parser generator. While I can't tell you how to solve it, I'd look to the size of your PHP pages as an issue. Do you have lots of includes?
Edit: I downloaded the source code for Bison (the yacc clone used by Linux), and looked for yy_create_buffer. Seemed pretty harmless. There is a variable for that controls buffer size, but I don't see any command-line option to set it. It's possible that whatever you're using is calling directly into the Bison library and not properly cleaning up.
set
memory_limit to -1
in your php.ini, for a workaround
or update your php version
should solve the problem
