Hi, I've upgraded from XE2.6 to XE3.1, and found I couldn't export to PDF anymore - not enough memory. So I increased the amount of memory for jetty to 720mb (it was already 512). I found after working with the wiki for maybe 30 minutes, something else would run out of memory. So i have to restart jetty every 20 minutes sometimes. I can only tell I have a problem when I start getting "can't parse vm whatever code" messages in the webbrowser. I'm not sure if this is a memory leak issue... I found that repeatedly clicking Export (in export-PDF) would increase the resident memory (in linux) all the way up from maybe 130mb to 1008mb (the virtual memory size) in jumps of over 50mb. Further clicking on the Export would would not increase the resident size, so I'm not sure what is going on there... is this a sign of a massive problem? cheers Paul
