Device not responding

[RKRam]

Hi Team /Experts,

1. Web management is failing on the primary unit.

2. We tried restarting the httpd, which fixed it for around 30 minutes, then issues came back.

3. We did failovers, and the new primary unit started having the same issues, and new secondary got fixed. Seems to happen only to the current primary unit, so at the end we fail back to Node A, as it was before.

4. Sometimes the unit responds and gets accessed, but the GUI is slow and suddenly it disconnects.

We found the max connections clients is reached, so we increased it to 20 as recommended, however we are still getting the same issues, should be increase it even more than 20? Please advise. Please help to fix this issue.

Looks like issue with OS. not sure if this is real issue? Can you open support ticket for more debug.

Can you check the device uptime, if device is up then 365+ days then i would recommed to reboot during off business hour.

When you say disconnect, do you mean thrown logged out ?

or something like

"Please wait while the Configuration Utility Start" / "Unable to contact the device"

Can you check in  /var/log/tomcat/catalina.out for any OOM logs

[boneyard]

does max clients of 20 make sense for your environment?

check with tcpdump where all those sessions come from, perhaps a script or monitor server going wild.
