Memory Exhausted error

Hi Community
I am relatively new at using CB so have a lot to learn still... I am setting up a site which includes:
Joomla 1.7.2 on Ubuntu 10.4
PHP 5.3.2
MySQL 5.1.41
Apache 2.2.14
CB 1.7 upgraded to CB 1.7.1

Since upgrading I am able to view com_profiler page and most of tools page, everything else gives me 500 error which I traced back to memory exhausted after checking logs/switching on debug etc.
I changed php.ini to serve up 256Mb (even 512Mb) instead of 128Mb but that has not helped. The error is reported as happening in .../com_comprofiler/library/cb/cb.acl.php on line 449.
Inside "get_group_parent_ids" function, inside (checkJversion() >= 2) logic...
Can anyone give me suggestions as to where to add more debugging to find out why it seems to dig a very big hole for itself?
Regards

Are you suggesting that a basic CB installation will require more than 1Gb of memory for PHP process???
I have changed the PHP settings as stated in my OP, including restarting/reloading apache to make sure it takes effect, even tried changing to 1G and it still falls over - feels very much like a loop somewhere and I don't know where to start checking in the code. I was hoping for some kind comments as to what the ACL does when it is looking up details at this point in the code...
I have defined approx 10 groups most of which were still empty as my userbase on the site is only 3...

No, I did not suggest this anywhere.

Things I do not know (because you haven't shared them): What is the exact error message you are seeing?

The reason I referred you to the FAQ and Tutorial section is that in most cases PHP settings you feel are valid are not in fact used.

but stating your exact error message would help.

Thanks for your patience - Sorry for being short but it's been a long day that is going to continue growing longer for the rest of this week

PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 523800 bytes) in ..../administrator/components/com_comprofiler/library/cb/cb.acl.php on line 449, referer: http://xxxx/administrator/index.php?option=com_comprofiler

with the appropriate size changing according to whatever I set in php.ini.

I have gone back to my standard 128M

I tried removing the module, removing all xxx_comprofiler_xxx tables and re-installing but got the same error again

I have had the exact same setup on a virtual machine - same versions of everything installed (well, as close as I can get) which worked fine.

I will remove again and try install previous version to see if that makes a difference...

Ok, went back to 1.7.0 and could get into the configuration, tools, plugin management, list management tabs but not the User/Tab/Field management tabs.

Each gives the same error as above, same line etc.

Also just noticed "sh: convert: not found" in the apache2 error.log file too... I presume that is something to do with someone trying to use imagemagick..??
