Dear Sirs, I don't know if this is the correct e-mail address for questions about bugs/crashes. I hope not to disturb you too much! I have a system composed by: >)ASUS P2B Motherboard with 384 MB SDRAM PC100 and a Pentium II 400MHz; >)Adaptec 2940UW with: >)4 UW SCSI IBM disks 9GB DDRS-39130W (id:1,2,3,4); >)1 UW SCSI IBM disk 4GB DCAS-34330W (id:0); >)1 Exabyte SCSI 4/8 GB EXB-85058HE-0000 (id:5); >)Etherexpress Pro10 plus; >)S3 ViRGE/DX 4MB; It crashes when the users try to allocate more than the physical memory. Today happend with 3 users trying to get 150+150+100 MB of physical memory.
