You mention that, mysqld AND mysql. You will note above that when I checked mysqld with fstat, there were only 64 files open. That, coincidentally, is the default proc.curproc.rlimit.descriptors.soft setting. Does mysqld fork they mysql process, which may not be inheriting the limits set for mysqld? Can I add a line in /etc/sysctl.conf to allow all processes to have a greater default soft limit for descriptors? Or could I recompile my kernel to change that?

sysctl process limitations
Environment:AlphaStation 255 w/ 64 MB RAM NetBSD 1.5.2 - custom kernel MySQL 3.23.47 I'm trying to load data into tables in a mysql database. When I feed the load script into the database it fails about 3/4 through. Error follows: SNIP ERROR 1105 at line 11: File ./geeklog/userinfo.MYD not found (Errcode: 23) /SNIP Looking at a few newsgroup postings, I beleive this is due to resource limitations. Specifically, I may have reached the max open descriptors limit. I've used the sysctl command to set all soft limits to unlimited, and still get the error. Here is the output of sysctl for my mysqld process: SNIP proc.4012.rlimit.cputime.soft = unlimited proc.4012.rlimit.cputime.hard = unlimited proc.4012.rlimit.filesize.soft = unlimited proc.4012.rlimit.filesize.hard = unlimited proc.4012.rlimit.datasize.soft = 1073741824 proc.4012.rlimit.datasize.hard = 1073741824 proc.4012.rlimit.stacksize.soft = 33554432 proc.4012.rlimit.stacksize.hard = 33554432 proc.4012.rlimit.coredumpsize.soft = unlimited proc.4012.rlimit.coredumpsize.hard = unlimited proc.4012.rlimit.memoryuse.soft = 57597952 proc.4012.rlimit.memoryuse.hard = 57597952 proc.4012.rlimit.memorylocked.soft = 57597952 proc.4012.rlimit.memorylocked.hard = 57597952 proc.4012.rlimit.maxproc.soft = 532 proc.4012.rlimit.maxproc.hard = 532 proc.4012.rlimit.descriptors.soft = 1772 proc.4012.rlimit.descriptors.hard = 1772 /SNIP According to this, I should be able to have 1772 files open...correct? I'm only trying to load data into 38 tables. And, IIRC, mysql only opens two files per table. So, I should not be encountering my descriptors limit. Any advice would be appreciated. TIA Cheers!
