I would say those logs are ZENworks Anti-Malware Specific since we use a Proxy to capture Anti-Malware Client Requests and redirect to OnDemand Content.  Its hard to say of OnDemand Content itself is having an issue on a larger scale.  Since restarting helps...I would suggest opening a support ticket...total guess but either a memory leak or maybe excessive timeout windows for connections or requests causing us to run out of connections.

Hi David,

I am wondering if there are any updates on this?

Thanks and regards

Hi, 

you have two options. install latest FTF , currently FTF-94 or do these changes ( got it from support )

Locate a file named `application.properties` in the folder `/etc/opt/microfocus/zenworks/zen-api-gateway/`.
Open the file and add the line `server.netty.idle-timeout=4500000`
Locate the file `/etc/opt/microfocus/zenworks/settings/zenapigatewaysettings.sh`.
Find the line `JAVA_MAX_HEAP=-Xmx1024m` and modify it to `JAVA_MAX_HEAP="-Xmx2048m"`.

I installed FTF-93 and looks like it fixed the problem. Server uptime is 37 days.

FYI....FTF 93 and 94 are the same with the lone exception that 94 fixes some issues getting appliance patches if you installed the Appliance using the new 23.4 ISO.  There was a missing file on the new appliance to allow for proper Appliance (not ZCM) updates.

If you are seeing any HPROF (aka crashes) around API Gateway try increasing the memory.  The next update will be increasing the default from 1GB to 2Gb as shown.

Both are good things for anyone to do.  (Note: 16GB of Memory is starting to cut things tight these days especially if your server is hosting the internal DB.  If it is ...I would be looking at 20GB minimum for that server.)
