I've identified 3 PTFs that may have changed TELNET/SSL behavior.
All applied.
MF61242
MF61847
MF62316
We've had several failures since the July 4 IPL and PTF apply.
Rocket has been unable to determine root cause.
Also have open PMR with IBM Comm group.
Yesterday, we disabled SSL for this app temporarily, now using port 23 instead of 992.
Also started a TRCCN.
Waiting for next failure, if any.

Subject: Rocket LegaSuite 5250 Gateway for Windows having intermittant timeouts/crashes when connecting to iSeries
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.
iSeries - Pencor05
V7R1 - TL16120, all latest group PTFs
