Hi, I just ./stop and ./start'ed two Zope servers that were taking up rather a lot of memory; PID USERNAME THR PRI NICE SIZE RES STATE TIME CPU COMMAND 841 nnle 12 33 0 395M 318M sleep 177:24 0.00% python 834 nnle 9 23 0 531M 14M sleep 101:20 0.00% python Is there any way of telling what objects are taking up this memory - could it be a memory leak in Zope at all? I'm using src-2.1.3 on Solaris because I still use the /REQUEST hint to see what my variables are. cheers, Tone. ------ Dr Tony McDonald, FMCC, Networked Learning Environments Project http://nle.ncl.ac.uk/ The Medical School, Newcastle University Tel: +44 191 222 5888 Fingerprint: 3450 876D FA41 B926 D3DD F8C3 F2D0 C3B9 8B38 18A2
