Issue/Introduction

All jobs may suddenly appear to have been stuck in READY.  New jobs tend to run but take a long time to complete.

Overall performance has degraded and restart does not help.

Cause

If jobs stay in READY state for a long time then there can be several issues.  The most common issue is when agent communication is blocked.  Check this KD link for any agent or network related issues.

If the network communication is not a problem then check for any local OS and DB issues.  The following is an example of local OS (AIX) discarding the packets, which can lead to "listener's queue full" issue

netstat -s | grep -I discarded
0 discarded for bad checksums
0 discarded for bad header offset fields
0 discarded because packet too short
473 discarded by listeners
0 discarded due to listener's queue full
0 output packets discarded due to no route
0 output packets discarded due to no route

 

Environment

Release : 12.0

Component : CA WORKLOAD AUTOMATION DE (DSERIES)

OS: Any

Resolution

Restarting will temporarily clear the queue and may resolve the issue.  Contact the System Administrator/vendor for any OS patches.
