Message-ID: <104@slu70.UUCP> Date: Sat, 22-Sep-84 14:11:32 EDT Article-I.D.: slu70.104 Posted: Sat Sep 22 14:11:32 1984 Date-Received: Thu, 27-Sep-84 03:32:12 EDT Distribution: net Organization: Saint Louis University ,St. L.,MO. Lines: 18 I recently installed 2.9 on a new 11/73 system. Relevant parts: 73 processor, 1M PEBX ECC memory, DILOG 228 disk controller with Fujitsu Eagle, DILOG 132 tape coupler with Cipher 891, DLV11J SLU all in a BA11SA box. After careful mods to the boot and kernel 2.9 runs like a champ ... except one in every three or four user processes dies just after birth with bus error, segmentation fault, IOT trap, or illegal instruction and the requisite core dump (bus error and seg fault most common). The frequency is load dependent. I've substituted the processor and memory; no fix. Others around me are not having the problem; they have Emulex controllers and Fujitsu 160's, though. The kernel has NEVER crashed in one month of operation. Has anyone seen this problem before? All suggestions welcome. My forehead is becoming badly calloused.
