P6 Out of Memory Error in Citrix Environment

Question

We are using P6 V7 in a Citrix Environment. One of our users is currently experiencing an "Out of Memory" error when he is linking activities. He has also experienced the problem when deleting or copying WBS Elements (containing up to 600 activities).
The only time that I have seen this error is when trying to import more than 2000 or so Activities from XLS at a time.
The project that he is working in currently has around 10000 activities.
Has anyone else had this problem? And, if so, found a workable solution?

Answer 1

Does it only affect the one user? Can somebody else perform the same functions without error? If so, his user preferences are probably corrupt. Reset them using the following SQL:
Update userdata set user_data = null where topic_name = 'pm_settings' and user_id in (select user_id from users where user_name = '<username>');
where <username> is the user's P6 username.
