Hi all

I have been encountering a significant performance degradation with EGW in the last 24hrs. The only system or global setting I directly changed was some email server connection information, but now all of the modules are very slow in responding to selections (ie clicking on Calendar or Resources leads to a very long wait, often minutes, before the module loads.

I have checked the underlying server (ClaerOS) and there is plenty of RAM available, and no process is consuming the CPU, and there is no disk-swapping occurring. Other services and applications on the underlying OS are performing normally.

The EGW logs are not showing any errors, and I don’t know if there is any performance logging in the EGW utility set. I do not know how to check performance on the underlying MySQL d/b.

Any pointers greatly appreciated

regards  
Ken

Hi all

As a follow-on to the previous post, it seems that EGW is performing normally when accessing modules UNTIL I try to access Felamimail. This module is no longer loads, it merely stays with hourglass icon and no activity.

Any attempts to load other modules AFTER trying email also fail. I have to close the browser window, then re-connect & login to be able to access any of the modules.

This is the Email server profile list:

Description - global  
SMTP server name - 142.25.56.13  
imap server name - 142.25.56.13  
Application - Any application  
Group - Any group  
User - any user  
Active - Active

This behavior seems to have started shortly after I tried to configure the ability for a user to access an IMAP account that was not the same username/password as the EGW account.

Ken

Hi all

As a follow-on to the previous post, it seems that EGW is performing normally when accessing modules UNTIL I try to access Felamimail. This module is no longer loads, it merely stays with hourglass icon and no activity.

Any attempts to load other modules AFTER trying email also fail. I have to close the browser window, then re-connect & login to be able to access any of the modules. If I do not try to load Felamimail, but just try to go to the email preferences, there is a very long wait before the page loads (over 1 min).

This is the Email server profile list:

Description - global  
SMTP server name - 142.25.56.13  
imap server name - 142.25.56.13  
Application - Any application  
Group - Any group  
User - any user  
Active - Active

This behavior seems to have started shortly after I tried to configure the ability for a user to access an IMAP account that was not the same username/password as the EGW account.

Email is a key application here, and my push to have EGW as the groupware solution for our whole organisation is at risk if I cannot get this sorted. Right now, while other modules are accessible, the moment I try email, all modules become inaccessible.

I am not a programmer or even very good with scripting like php, so I don’t even know where to start looking. The server host logs don’t show any errors (that I can find) related to php, eGroupware, of failed connections. The Email server has not experienced any issues, and staff are sending & receiving fine with their own clients, such as Thunderbird.

All I need is a quick & dirty fix; is it possible to uninstall & re-install just Felamimail? Is there a chance this would fix the problem?

regards  
Ken

Hi Kenneth!

Which egw version do you use? I experienced felamimail to take a pretty  
long time to load an imap inbox after an update 1.6 -\> 1.8 But after  
this initial felamimail delay everything works again. I use nonencrypted  
imap on localhost.

Hi

We are using 1.8, and all was good for months, up until I tried to allow users to set different email accounts. I also am unencrypted IMAP, but connecting to remote host

On my home page, I now see this: (need to view this email in html, not plain text)

eMail  
can’t connect to INBOX!!

With my email server profile set as below, as I understand it, my EGW login credentials should be applied in communicating with the server and accessing IMAP. That is how it WAS working before.

regards  
Ken

Hello all

Update on this issue:

I was able to salvage our working EGW install - I collected email server information from an older Virtual Machine image I had used before going live (backups WORK!)

Sorry to bother everyone. This was a self-inflicted problem from incorrect settings.

regards  
Ken
