Howdy, I recently upgraded an old box running 4.6.2 to 4.9-p4, and found that afterwords, Postgres was hanging due to kern.ipc.shmmax being way too low (4096 bytes, or one page). The line in the kernel config (as confirmed by LINT) was this: options SHMMAXPGS=8192 # max amount of shared memory pages (4k) options SHMALL="(SHMMAXPGS*PAGE_SIZE+1)" options SHMMAX="(SHMMAXPGS*PAGE_SIZE+1)" Thinking perhaps this was no longer valid, I tried again by doing the math myself, but I got the same result; kern.ipc.shmmax=4096. For now I'm just setting this in sysctl.conf, but I'm curious as to what has changed, or what I'm doing wrong. Thanks, Charles -- Charles Sprickman spork@inch.comhelp
