Обсуждение: More on Too Many Open Files... NetBSD
Having no idea what i am looking for, I find... bash-2.05$ ulimit -a core file size (blocks) unlimited data seg size (kbytes) 131072 file size (blocks) unlimited max locked memory (kbytes) 168714 max memory size (kbytes) 506144 open files 64 pipe size (512 bytes) 1 stack size (kbytes) 2048 cpu time (seconds) unlimited max user processes 80 virtual memory (kbytes) 133120 bash-2.05$ sysctl kern.maxfiles kern.maxfiles = 1772 This looks like all is well?

Ulimit controls the maximum number of open files per process while sysctl controls the maximum number of open files system-wide. I would look at sysctl. However, if the number of system open files is low, I would think you would see problems in more places. Is it possible your command-line is trying to open an infinite number of files? Can you send us your command line? -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 853-3000 + If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania 19026
The command from inside the pltcl function? It is wrapped in a loop that should run about 200 times and is
exec echo $msg | mail -s "New Timecard System" -c "ianh@tpchd.org" $U(username)@tpchd.org
where msg is a little message.
I start postgresql with default values.

Ulimit controls the maximum number of open files per process while
sysctl controls the maximum number of open files system-wide. I would
look at sysctl. However, if the number of system open files is low, I
would think you would see problems in more places. Is it possible your
command-line is trying to open an infinite number of files? Can you
send us your command line?

Each PG backend can open a lot of files with a large database. I'd try cranking it up in the script that starts PG. > bash-2.05$ sysctl kern.maxfiles > kern.maxfiles = 1772 If this is the systemwide limit it also might be a bit low. It's more likely to be the ulimit that's biting you though. -Doug -- Let us cross over the river, and rest under the shade of the trees. --T. J. Jackson, 1863
Hi, I think you should read login.conf(5) on that netbsd box of yours. http://www.tac.eu.org/cgi-bin/man-cgi?login.conf+5+NetBSD-1.5.1 It looks like you file limit is about right for a default login class look at /etc/login.conf if it exists on your system.. -- Matt Sauve-Frankel Philosophie Bleue | http://philosophiebleue.com Network Administrator | http://pblue.com -- An idea is not responsible for the people who believe in it
Hi,
from /usr/local/share/doc/postgresql/README.OpenBSD
on my OpenBSD 2.9 box
-snip
The ulimit settings can also be a problem. The following can be
added for the postgresql user in the /etc/login.conf file:
postgresql:\
:maxproc-max=256:\
:maxproc-cur=256:\
:openfiles-cur=768:\
:datasize-max=256M:\
:datasize-cur=64M:\
:stacksize-cur=4M:
For more than about 250 connections, these numbers should be
increased. Please report any changes and experiences to the package
maintainers so that we can update this file for future versions.
-/snip
you can assign a user to a login class by entering into the 5th field of your
passwd file. (edit it with vipw) check passwd(5) to be sure
postgresql:*:1013:1013:postgresql:0:0:PostgreSQL:/var/postgresql:/sbin/nologin
