I've started to use the head version of drush and got a problem I cannot solve. Drush returns the tipical php.ini memory error "Fatal error: Allowed memory size of 16777216 bytes exhausted ". However, php is running with 1000M!! I checked the php.iuni used by the server. It's ok as it shows phpinfo. The drupal it selfs is running fine with no problems, but drush doesn't.
I have two drupals installed in this server: a drupal 6 at the root and a drupal 5 installed in a subfolder of the D6. Could this be confusing drush?
