Work Processes Stucked and Lock table error

148 Views

Hello Expert,

We are using ECC 5.0 640_EX2 Kernel and patch level 304.

For Production server we are using Cluster HA scenario.

We have DB CI in cluster and 18 apps server connected to CI.

We faced following problem repetative time on this server

Problem : Not able to login CI server.

Observation : 1. All DIAG WPs are stuck on CI server

DIAG WPS in running state but nothing is running actually (No reports nothing shown)we tried to kill few DIAG WPs but not released. We monitored this at OS level (AIX 5.3) using DPMON.

2. Lock error found in SM21 log

There was no more activity possible on server as no more lock possible and lock error occuring.

Issue resolved after restart of the CI server and manually clean of IPCs processes.

Kindly let us know where and how can we check the reason for such incident and precautions we can take?

Is this any know issue? and what can be the reason?

Regards,

Nitin Salunkhe
