Creating and terminating user account taking too long

Havri · May 23, 2017

Hello,

I am encountering an issue with the creation and deletion of accounts on a few servers. I removed one account using the command line. The line that the process was stuck is:

Removing HTTP Virtual Hosts......

Here is the output from the command line:

Code:

The same thing applies when creating new accounts. I've added a screenshot from the WHM interface that shows the same httpd.conf problem.

Is anybody experiencing the same issue? Is there a solutions to this? The problem is not reproducible each time. Sometimes it takes 10 seconds, sometimes 100.

Thank you.

If its not for all account that you delete then make user to check if there are some files or folder with chattr permission set.
While creating account did you check the server load? if there load is high even that can cause slow creation of account.

Havri · May 23, 2017

Hello,

This applies even if I create a new account and then try to delete it, so there is no selective treatment only for some users (no chattr permission set). The account is new, so this means no chattr and no load on server (as there are only a few users). My `uptime` command outputs the following:

Code:

 13:44:20 up 89 days,  1:50,  2 users,  load average: 0.90, 0.95, 0.99

Thanks.

Hello,

Could you verify which version of cPanel is installed on this system? You can check with the following command:

Code:

cat /usr/local/cpanel/version

Thank you.

Havri · May 24, 2017

Hello,

Sorry for the delayed answer. The version is:

11.64.0.22

I just recreated the account and removed it. Both operations were done from the command line. It took over 1 min to erase one empty account. The server runs only SSDs, so there isn't an I/O bottleneck.

Code:

[root@server04 ~]# time /scripts/removeacct subdomain

Thank you.

To update, it looks like the delay stems from CageFS functionality taking an extended amount of time during the account termination process.

Thank you.

Havri · May 30, 2017

Hello,

I also replied to the cPanel ticket and I don't think that CageFS is the one that delays the account termination. Please see my answer from the ticket.

Regards.

i-Strategi · Apr 30, 2018

I have the same issue. Also had it before i started using CageFS so im very sure that's not the issue.

Did you manage to locate the issue?

@OP - why answer to ticket? Should have been answered here so we (who has the same issue) can read the solution instead of asking again.

Hi @i-Strategi,

Support ticket 8520305 looks to have been an isolated issue with LiteSpeed that we were unable to reliably reproduce. If you notice delays during the account or termination process, please feel free to open a support ticket using the link in my signature so we can take a closer look at an affected system. You can post the ticket number here and I'll update this thread with the outcome.

Thank you.

Havri · May 22, 2018

Hello,

I've reviewed the ticket from cPanel support and it seemed that two services were using file-lock on the httpd.conf file. Of course, that was the issue then. After updating cPanel and Litespeed, all went well.

What you can do is strace the account termination process from the command line:

Code:

strace -tt -T -ff -o my_output.file -s 4096 -f /scripts/removeacct my_domain

Of course, this is just an example. You can tweak it as you'd like. Maybe this will help you find the problem.

Good luck.

Hello guys,
I`m facing some sort of issue but strange one.
Mine one i think is fast when creating account and delete them but the big problm is when creating/terminate account my entire websites they dont work for aroung 1 minute.

This is start to be big pain when daily make 20-30 operations, the customers start to complain about this and i dont understand why it makes like this in the last mo. Even me i start to get angry cuz i have to allways whait and whait lot of time so the websites start to work again.

This happen even if i make in the night time operations and the load is 1-2% even in the day when load is 3-4%

justtesting account removed

real 0m9.872s
user 0m1.066s
sys 0m0.321s

Can someone give me a hint or sompting where to and what to check ?

Thank you.

cPanelMichael · Jul 12, 2018

Hello @Bidi,

Can you open a support ticket so we can take a closer look at the affected system? You can post the ticket number here and we will link this thread to the ticket.

Thank you.

Hello Everyone,

I'd like to follow-up with anyone here that reported poor performance when creating and terminating accounts.

cPanel & WHM version 76 offers significant performance improvements in this area of the product that should alleviate the concerns reported on this thread. We've also made some additional performance improvements in version 78 (available in the CURRENT release tier at this time), with even more improvements planned as part of version 80.

Feel free to reply to this thread with feedback on the performance of account creation and termination upon upgrading to these versions.

Thanks!
