I am getting an error about to many open files. I tried to "echo 500000 > /proc/sys/fs/file-max" The number is there now, but I continue to get the error. Is there something else to do? Jerry

I have coded up the standard sendfd() and recvfd() for linux to send and recv file descriptors. seems to work (http://book.chinaunix.net/special/ebook/addisonWesley/APUE2/0201433079/ch17lev1sec4.html) however when I recvfd() my number of open file descriptors bumps by 2 and not 1. (using lsof -p X | wc -l) I am not sure why the count jumps by 2 and not 1. The sendfd() is just sending a socket

Hi I have a compaq R4000 with the 2.4GIG AMD 64 bit. 4000+ rated. proc cpuinfo reports cpu Mhz as 997.481 Do I have to run the 64 bit version to have things run correctly? I just have the normal 4.2 loaded at this time. The laptop seems slow for 4000+ as reflected by the cpu Mhz also. Any thoughts on running the 32 bit version of 4.2 vs the 64 bit version of 4.2? Jerry

Hi - I am not an expert at shell script writing. If /proc/cmdline looks like option1 option2 ... ks=http://192.168.1.8/ks/ks.cfg option3 option 4 ... How can I get the 192.168.1.8 out of this cmdline. THanks, Jerry

Is there a command that will monitor a process for exiting (crash or normal exit) and then execute another command based on the said process no longer being active? Or is there a "wrapper" command that runs a process and when that process exists due to crashing or just exiting normally) that another process can be run. Thanks, Jerry

hi all I have something like 3000 log files in a directory (from data collection). At 4am in the morning cron runs a script of mine that essentiallly trims all files in that directory back to a certain size. Basically does a "tail -c XXXX filename > tmp_filename" I have noticed that only around the 4am-4:15 time frame when the trim is happening does my other process log connection

So I have a problem that I'm trying to get through, and I just can't seem to get it to run very fast in R. What I'm trying to do is to find in a vector a local peak, then the next time that value is crossed later. I don't care about peaks that may be lower than this first one - they can be ignored. I've tried some sapply methods along the way, but they all are slower.

I was just wondering if there are special tricks people do that compile A LOT on centos? Do RAM disks help or something else I dont about that minimizes your compile time? I presently have and AMD x2 4800+ with 2GIG ram. Just curious if I can reduce any more time out of my compiles. Jerry

Hi ! I have a server (Centos 5) that is using a pair of SAS drives to store the data. (Mail server) They are on an adaptec raid controler with a battery backup and write back cache active. >From time to time, I have sever peak io to those data disks (> 400 to 500 iops, > 70 to 100 megs/sec). With iostat, I find that it's almost a write i/o problem. How can I find to which files
