Upgraded the size of a server in Azure to F4 (from a B1) and now Virtualmin takes 20+ seconds to load pages related to the Virtualmin virtual servers. Webmin pages and actions all load less than a second. But try to load the list of the 11 virtual servers and it takes 60s. The server is not that busy and all of the virtual servers are perfectly responsive. A mix of web sites, APIs, and MySQL DBs. It’s as if something in Virtualmin got corrupted or lost it’s ability to have anything but the tiniest slice of CPU time.
Using Edge dev tools network tab looking at clicking the “List Virtual Servers” link:
Here’s the versions:
Operating system CentOS Linux 7.9.2009
Webmin version 1.973
Usermin version 1.823
Virtualmin version 6.16
Authentic theme version 19.73
Processor information Intel(R) Xeon(R) Platinum 8168 CPU @ 2.70GHz, 4 cores
CPU load averages 0.09 (1 min) 0.14 (5 mins) 0.14 (15 mins)
Real memory 4.41 GiB used / 2.34 GiB cached / 7.79 GiB total
It’s not the browser because I tried other browsers and get the same results. Also have other Azure servers running Virtualmin and not having issues there. Also verified same slowness with “Gray framed theme”.
I’ve looked everywhere for a setting that might have changed or something different on this server compared to other servers - and I come up dry. Not sure where else to look or how to further troubleshoot this issue. Is there a script to run to repair Virtualmin? Other ideas?
