We installed Moodle on two different servers for two diffferent applications. Both installs went very smooth. Both are small, old, low budget systems. When we created a class on each, we got the following error message. The same message except 136 = 64 on the other computer. The system for the error message below is a K2350 with 256Mb RAM and it think is has a 13MB drive. This system is also running phpBB2. At this point we are just trying to get some experience with Moodle and are not yet trying to run production classes.
Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 184320 bytes) in /var/www/html/moodle/mod/workshop/lib.php on line 2354
Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 136 bytes) in Unknown on line 0
We are running 1.2 Development 20031226 on RH 8.0.
Other than shooting the computers, do you have any suggestions.

Added Note: Now that I have posted this note and now found all the others with the same issue, is the answer to set memory_limit to 16M? Or is there something else to try?
Thanks
Robert
