I run inte error trying to start the xqmagent.sh. I have downloader the latest version so the startscript is the wrapped version.
I run Redhat 9 (which I'm not very familiar with, or Linux in particualar for that matter...)

When I try to run ./xqmagent.sh the process starts to spawn (I guess) a bucnh of child processes but after a while it stops with the message

QUOTE

./xqmagent.sh : fork : Cannot allocate memory

At this time (checking for example ps -a) I see that there are about 100 processes for xqmagent. I am running many mail accounts, about 60, but all these processes?

Regards
Björn

The max. no. of threads you should see should be 27 or - after your changes 6 threads. The Agent's hard limit is 25. So some hundred threads is rather strange ... How much RAM do you have? What is the output of the 'top' command, right after starting the Agent ? Run the Agent in debug mode, to see if it gives back any errors: killall --KILL xqmagent ./xqmagent --debug -------------------- Bye, Harald -- Download XMail Queue Manager 1.46 NOW: XMail Server Tools -- Cross platform remote queue management! -- Message analyzing on the fly! -- Builtin diagnostics knowledge base! -- Manages multiple mail queues!

I have to say it is pretty strange to me too :-) And not in a good way...
The amount of ram I must honestly say I don't know how to check. I only manage the server via SSH and I'm don't know all the low-level linux commands (yet, and will never do for that matter :-)

The only I could think of was the command "free" which gave me :

Swap: 1044216 91092 953124

I now tried two things

1) I ran ./xqmagent.sh -- debug & and then top with the following result (I did remove a few HTTP here since I didn't think these where of interest)

The system stopped to respond and I have to kill everything to come back to life again. Nothing out of the debug!

2) I ran ./xqmagent.sh and waited a while. Then I opened another window and checked the processes. The result -> ps -a

Oooops, does NOT look so good. Ofcourse, the system stopped to respond again etc etc...

This is my xqmagent.sh

CODE

#!/bin/sh
#
# Use this starter script, if you are on RedHat >= 9.0.
# This forces your kernel to use the older standard thread scheme.
# If you don't use RedHat, you are free to start ./xqmagent directly.
#
export LD_ASSUME_KERNEL=2.41
./xqmagent.sh $1

and my xqmagent.conf (with the comment removed)

QUOTE

#!/bin/sh

export LD_ASSUME_KERNEL=2.41
./xqmagent.sh $1
[root@roquez xqmanager]# less /etc/xqmagent.conf

THREADS=4

STARTSCRIPT = /etc/init.d/xmail

AGENT_HOST = 127.0.0.1

AGENT_PORT = 8000

AGENT_DYNIP = 0

TRUSTED_CLIENTS = 127.0.0.1,tbird,192.168.0.*

CTRL_HOST = 127.0.0.1
CTRL_PORT = 6017

I just checked the server status logs and found :
May 3 14:23:07 roquez kernel: VFS: file-max limit 52416 reached

Something is rotten here... and I guess I'm the thief.. but how where and why?

Thanx for your great patience,
regards

Björn

Output -> ./xqmagent --debug Agent version : 1.40 Using xmaillib : 1.54 Using rpcserver : 1.12 Configurationfile : /etc/xqmagent.conf Threads : 4 Listening at : 127.0.0.1:8000 CTRL access at : 127.0.0.1:6017 Trusted clients : 127.0.0.1,tbird,192.168.0.* Handle dynamic IPs : No PID : 16862 Parent PID : 16409 which I guess is good :-) I'll try to get on from here now, Thanx for the help
