We have a remote web app that connects to the i-Series using Rocket's LegaSuite Integration 5250 Gateway for Windows and Legasuite Distributed Engine.
The app has been running for years with virtually no issues, 100,000+ requests daily.
Latest CUM TL16120, all latest group PTFs were applied on July 3.
Recently, we are seeing intermittent timeouts, sometimes with failures, thus Rocket services need to be recycled.
We have a severity 1 case open with Rocket.
Full logging has been turned on Rocket server.
iSeries does show any failures since the connection timeout.
Still looking for root cause,
Has anyone had or seen similar issues?
Multiple Telnet connections over port 992 using QPADEV* devices.
Connections remain open.
Addition connections made as needed.
Below is config summary and a snip from one of the failures.
