> Key: TRAFODION-2245
> URL: https://issues.apache.org/jira/browse/TRAFODION-2245
> Project: Apache Trafodion
> Issue Type: Bug
> Components: dcs
> Affects Versions: 2.1-incubating
> Environment: Testing trafodion when failures occurred. HDP 2.4
> distro contents and a standard installation on CentOS 6
> Reporter: Carol Pearson
> Assignee: Selvaganesan Govindarajan
>
> Dcsserver checks if Trafodion is running by using sqcheck. That can hang in
> some circumstances
> In this case we had a DTM failure and recovery took a while. The node went to
> a SoftDown state as the DTM recovered. Meanwhile, dcsserver was looking for
> trafodion to come up so that it could start the mxosrvrs on that node. That
> resulted in many hung sqchecks - the notable symptom is that they all had the
> same ppid.
