Issue/Introduction

When running an autoping command against a new agent install, it is consistently failing, but for inconsistent reasons.

Sometimes, the autoping will succeed for the Scheduler/Application Server, but not the other. Other times it will fail from both.

Environment

Release : 11.3.6/12.0

Component : CA Workload Automation AE (AutoSys)

Resolution

There are a variety of reasons that can cause this behavior. Intermittent success/fail for autoping almost always is due to a problem with the network. This resolution is just one example we found...

The net.ipv4.tcp_tw_recycle kernel tcp parameter was enabled and set to 5. Once this was set to 0 (disabled), the autoping started working.
