    Description

      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.
