Terminal Service Plus

We have had several instances where the HTML5 web server becomes unresponsive. When this happens. users start showing up in Task manager as disconnected and will eventually disconnect all users. The 2 servers that were affected today were Server 2016 / 8 cure / 28 GB. Around 20 users were connected at the time, another 10 on the other server. Running TSPlus 12.20.2.28

I read in another article about Java memory heap possibly running out of memory. modifying teh runwebserver.bat and adding -XX:+AggressiveHeap broke the SSL cert and had to remove the modification and reboot to get the web services running properly.

You run Java 64bit on Windows64 system - everything looks good!

Seems to happen about once a week on a server. Wondering if anyone has seen this before or if there is a good way to monitor java memory usage etc.

Hello,

could you please create new issue ticket and attach there your *Clients\webserver\web_log.txt
It is necessary to understand what causes it, probably you are getting DOS attack, however webserver is not made to prevent TCP level attacks, here you need proper firewall/router, but it must be investigated what could cause it.
