I'm trying to track down a memory issue with apache/php/odbc when talking
to Virtuoso.
The error is: "PHP Fatal error: Out of memory (allocated 3407872) (tried
to allocate 18446744073709551613 bytes) in..."
The actual line in PHP is: return (odbc_exec($this->db_link, $db_query));
The db connection was opened with: $this->db_link =
odbc_connect($this->dsn, $this->db_user, $this->db_pass,
SQL_CUR_USE_DRIVER);
The virtuoso odbc drivers in use were taken from the build of the database
being accessed (same architecture/OS on both boxen):
Virtuoso Open Source Edition (Column Store) (multi threaded)
Version 7.0.1-dev.3203-pthreads as of Nov 11 2013
Compiled for Linux (x86_64-unknown-linux-gnu)
Are there any current issues I should be aware of or is there any advice
you could offer about this?
The actual resultset is about 7 rows from a result set thrown by an sql
function via exec_result_names/exec_result but it seems to ask for quite a
lot of memory and I'm not sure our budget extends to exabytes of ram.
