The accumulation of these data structures can cause Out Of Memory errors. 03.disconnect takes 30 min, which stalls freeing data set locks 04.OpenRSE thread and MVSminer thread are in contention in writing traces onto standard.out. 05.data set lock not released when client ends due to NPE in finish processing java.lang.NullPointerException at org. eclipse.rse.internal.dstore.universal.miners.command. CommandMinerThread.sendExit(CommandMinerThread.java:1066) followed later by java.lang.NullPointerException at org.eclipse.rse.internal. dstore.universal.miners.command.CommandMinerThread. cleanupThread(CommandMinerThread.java:1114)
Problem conclusion
01.Now, the log problem is resolved 02.RDz host now discards older data structures (using the SPIRIT mechanism). 03.resolved by OpenRSE Bug 388873 - ServerUpdateHandler _senders list should be synchronized 04.Now, OpenRSE is changed so that it should not write any data onto standard.out 05.NPE is caused by _stdOutputHandler being null. The code has changed to accept a null value.
