Various, but perhaps just my install

[JoeMurray]

I'm not sure my svn install is working properly as I had an error when first trying to enable CiviCRM due to an incorrect value for $civicrm_root. I corrected that and was able to enable. I've also disabled and re-enabled CiviCRM to try to fix the following:

No CiviCRM menu item appears.

I can navigate to all of the Drupal admin items except People. When I go there, I get
Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 16 bytes) in /Users/josephmurray/Sites/civicrm/4.0.alpha1/packages/PEAR.php on line 884

Note that the Drupal install is at /Users/josephmurray/Sites/drupal-7.0, and there is a symbolic link from /Users/josephmurray/Sites/drupal-7.0/sites/all/modules/civicrm to /Users/josephmurray/Sites/civicrm/4.0.alpha1, so the error appears to be CiviCRM, or at least how I installed it.

You must increase memory_limit.

Joe, did increasing the memory solve your problem? I'm seeing the same issue, and my memory limit seems to be more than adequate.

[JoeMurray]

Increasing the memory did indeed solve this issue.

What's the value you ended up putting ? More than 128Mb ?!?

(am I the only one to find it very high) ?

I haven't played seriously with this setting to find the lowest that works. Some of this is that D7 has a larger need for memory than D6. I tossed it up to 512MB, and just tried bringing it down to 256MB. I'll post back if that is inadequate.
