NethServer Version: 7.9.2009
Module: Webtop - 1.7.1
I’m running the latest version of Webtop. No updates have been applied to my Nethserver for a couple of weeks now so nothing has changed on my Nethserver. We been running Webtop successfully for the past 2 years without issues.
On Monday (yesterday) my users started to notice that mail was slow. Slow to login and slow to navigate around folders and open mail. On Monday evening (last night) I noticed in the Webtop log an error that said:
java.lang.outof memory error
In Webtop Settings > Advanced Settings I saw a minimum of 512 MB and a maximum of 1024 MB. I doubled these to a minimum of 1024 MB and Maximum of 2048 MB. My Nethserver has 12 GB of Ram allocated to it (running virtually on Proxmox). Nothing has changed on Nethserver and nothing has changed on my Proxmox server. Last evening mail performance improved after I increased the memory settings in Webtop.
Our Webtop has the chat app enabled (more than a year ago now) and I’ve recently (2 weeks ago) added the Jitsi integration app to Webtop. Again nothing has changed recently on my Nethserver or my Webtop.
This morning my users are once again reporting that mail is very slow to use again. I’ve looked into the Webtop log file and I don’t see memory errors. There is nothing in the Webtop Log to indicate a problem:

Can the webtop team suggest any reasons why this slowdown has suddenly occurred? Where else I can look for why there is slowdown errors.
