http://newlisp.org is down again. This time its more serious that I can't reboot. They (ipowerweb.com) will try a hard-reboot but want to charge for everything else.
So I might have to look for a new provider and newlisp.org will be down for some time. This will also affect my email to nuevatec.com, so only contact me on the board via private message.

The GUI screenshot killed the machine ;-)
https://www.nearlyfreespeech.net/ has newLisp preinstalled :)
Thanks for the ISP tips. Currently this is my situation:
Before the reboot in apache/logs/error_log many of these messages:
[Thu May 31 14:55:55 2007] [emerg] (2)No such file or directory: Child cannot open lock file: /usr/local/psa/apache/logs/httpd.lock.233
after reboot I created a /usr/local/psa/apache/logs/httpd.lock
doing:
touch httpd.lock
chown apache httpd.lock
now whenever trying to restart apache I get in the error_log:
critical_create(): semget() failed: No space left on device
I deleted about 50 of apache/logs/httpd.mm.xxxx.sem where x is a number. Now when starting apache it creates a httpd.mm.xxxx.sem but I still get in error_log:
critical_create(): semget() failed: No space left on device
HELP
Lutz
ps: running Apache 1.3

Do you have a NSF mount or cluster-disk?
Remove the lock file that is automaticly created by "apache start" it contains the PID..
Check if there is no apache already running as i.e. Root? or is there still a Lock file around?
Any changes on the user rights?
..im thinking...
What does ipcs give you?
...it probably ran out of semaphore memory...
(which is very odd after a reboot)
http://www.forum.psoft.net/showthread.php?t=8428
I don't want to reboot, because I am afraid the machine won't and I have to call support again. For the moment I have newLISP serving a short page.
Is there any way to free semaphore space without reboot?
Lutz
you have to remove the semphores with "ipcrm"
first look at what ipc are oocupied with "ipcs"
make sure no apache is running (apachectl stop..or kill and clean up the lockfiles or apache.pid lock.pid ) then do ->
then you have to remove them one by one with
ipcrm -q MSGID (depends on yuo linux distribution i think..man ipcrm..)
But It could also be that one of the apache modules got screwed...
if you do a "ipcs" look for the CPID thats the PID that created the Sem.
But if there are more sessions on that system then it could very well trurn out that
there is still not enough reserved..then a kernel /proc update is needed with some
extention to /sem.
You can determine the amount of System V IPC resources available by looking at the contents of the following files:
/proc/sys/kernel/shmmax - The maximum size of a shared memory segment.
/proc/sys/kernel/shmmni - The maximum number of shared memory segments.
/proc/sys/kernel/shmall - The maximum amount of shared memory
that can be allocated.
/proc/sys/kernel/sem - The maximum number and size of semaphore sets
that can be allocated.
For example, to view the maximum size of a shared memory segment that can be created enter:
cat /proc/sys/kernel/shmmax
To change the maximum size of a shared memory segment to 256 MB enter:
echo 268435456 > /proc/sys/kernel/shmmax
Start of changeTo view the maximum number of semaphores and semaphore sets which can be created enter:
cat /proc/sys/kernel/sem
This returns 4 numbers indicating:Start of change
SEMMSL - The maximum number of semaphores in a sempahore set
SEMMNS - The maximum number of sempahores in the system
SEMOPM - The maximum number of operations in a single smeop call
SEMMNI - The maximum number of sempahore sets
I am on FreeBSD, ipcs gives me:
/proc> ipcs
Message Queues:
T ID KEY MODE OWNER GROUP
Shared Memory:
T ID KEY MODE OWNER GROUP
m 131072 5432001 --rw------- postgres postgres
Semaphores:
T ID KEY MODE OWNER GROUP
s 65536 0 --rw------- apache apache
s 65537 5432001 --rw------- postgres postgres
s 65538 5432002 --rw------- postgres postgres

s 65542 0 --rw------- apache apache
s 65543 0 --rw------- apache apache
s 65544 0 --rw------- apache apache
s 65545 0 --rw------- apache apache
But using on ipcrm on any of the numbers gives me:
/proc> ipcrm -q 65536
ipcrm: msqid(65536): : Invalid argument
/proc>

"ipcrm -s SEMID" thats the id you see with "ipcs" under SEMPHORE..
ipcrm -s 65536 should do the job...
-q if for the message queues..sorry..
YES, ipcrm -s did the job, http://newlisp.org is up again.
Thanks for saving newLISP Norman (get some sleep ;) )

Hey Jeff,
Do you use nearlyfreespeech? And if so, how do you like it?

It's a nice service, but only PHP runs embedded in apache. Everything else, including newLisp, is on CGI. They do not have FastCGI, either.
That being said, its an excellent service. I haven't used it much yet, but it is always up, fast, and you pay for the bandwidth you use. I've been pretty impressed because they actually do only charge you by your usage - it's not a gimmick.
For a huge site that gets a lot of traffic, I don't know. You would have to look at your actual numbers and calculate how much it would cost you to run. I have a feeling that if you have a significant enough traffic base, it might not be cost effective.
