WHMCS : CURL Error: 7 - couldn't connect to host

Setup > General settings > Security > API IP Access Restriction

I added both the IP's to the list. The main IP for the reseller account 10.10.10.10 was to be added onto the API list.

http://docs.whmcs.com/ResellerClub#CURL_Error:_7_-_couldn.27t_connect_to_host

However, this did not fix the issue.

The second fix was to check the settings for the server.

Setup > Products & Services > Servers > "Select the server" and click on edit settings button

Check whether all the settings are entered correctly and also check the settings for Secure access.

Check "Enable ssl mode for all connections"

This fixed the issue.

wrong server load

Recently for the CloudLinux installed server the server load is shown wrongly

for example :

load average: 2136406556.03, 2136819086.23,

This is a known bug in lve0.8.36 kernel where it reports such numbers and the way it handles load on scripts that are seemingly using large I/O. This is corrected with the command `sysctl -w abi.vsyscall32=0`.

OR

sysctl -w kernel.full_loadavg=0

Where previously the variable by default is 1. But this will take some weeks to set the normal load value on your server.But as per the CloudLinux we can fix the issue by update kernel to newer version that is available via:

# yum update kernel
Do it your own risk :)

That is reboot into newer kernel (lve0.8.44).

Thank you,

to clear memory cache

If your server using all your memory and you have no available memory you can safely run this command to clear the memory cache




sync; echo 3 > /proc/sys/vm/drop_caches

http is not running

Apache not running, httpd is down
[~]# service httpd restart
httpd not running, trying to start


Then i have checked the http error lod and found the following error

[Wed Oct 25 00:00:00 2011] [error] (17)File exists: Cannot create SSLMutex with file `/usr/local/apache/logs/ssl_mutex'
Configuration Failed

Solution:
cd /usr/local/apache/logs/
mv ssl_mutex ssl_mutex_ajeesh
service httpd restart

This fixed my issue.

mail sending failed

2011-09-10 16:30:09 lowest numbered MX record points to local host: tuxunited.com (while verifying from host mail-yx0-f179.google.com [125.12.125.125])
2011-09-10 16:30:10 H=mail-yx0-f179.google.com [125.12.125.125] F= temporarily rejected RCPT >: lowest numbered MX record points to local host

Solution:

First need to remove the particular domain name from

/etc/remotedomains

and add the domain name in

/etc/localdomains

That is all fixed my issue
