High CPU consumption by jproxy process

thesasuser — Mon, 29 Sep 2025 17:37:19 GMT

Hello
We have SAS installed on Windows Server and Clients connecting using SAS EG.
I have observed that often when a users runs SAS code, a jproxy process is created.
often this consumes higher system resources.
In the instant case one jproxy process alone was consuming 75% of the CPU and the code was something like this

ods graphics on;
proc reg data=&in.(where=&where) plots=diagnostics(unpack) PLOTS(MAXPOINTS=2800000); model m1=%temp/abc; run;
proc reg data=&in.(where=&where) plots=diagnostics(unpack) PLOTS(MAXPOINTS=800000); model m1=%temp/cde; run;

Can somebody help me understand what is jproxy and why this high CPU consumption?
Is there a way to handle this type of case more gracefully?

I found this:

"...an additional JProxy session is started when a user runs an interactive task that has any graphic results. The JProxy session remains active and is used for any additional graphic results until the interactive user signs off or the SAS Studio session times out."

You may want to open a track to SAS support, they might be able to help you troubleshoot the excessive CPU usage.
