Description

One of the derby database table "gets corrupted"/"indicates connection not available" during processing inserts from java client application as shown in the trace and the only way to recover from this error is to rebuild the DB - by deleting the data and creating the tables again. This happens once in a while (thrice in a span of two months) and the java application (run in multiple servers), which updates the database, processes around 100 million transactions per hour (in total and each transation results in 4-5 updates to the DB)

There are eight tables in the derby database.

TABLE NAME ROWS COUNT (at time of corruption)
---------------------------------------------------------------------------------
KPI.KPI_MERGEIN; 362917
KPI.KPI_IN; 422508
KPI.KPI_DROPPED; 53667
KPI.KPI_ERROR1; 0
KPI.KPI_ERROR2; 2686
KPI.KPI_ERRORMERGE; 0
KPI.KPI_MERGEOUT; 362669
KPI.KPI_OUT; 125873

The derby database has been started with the following parameters

CMD="java -Dderby.system.home=$DERBY_OPTS -Dderby.locks.monitor=true -Dderby.locks.deadlockTrace=true -Dderby.locks.escalationThreshold=50000 -Dderby.locks.waitTimeout=
-1 -Dderby.storage.pageCacheSize=100000 -Xms512M -Xmx3072M -XX:NewSize=256M -classpath $DERBY_CLASSPATH org.apache.derby.drda.NetworkServerControl start -h $KPIDERBYHOST -p $DERBY_KPI_PORT"

The corrupted database tar (filesystem) in live environment was moved to a test system (Solaris system) and few checks were run on the corrupted DB as part of analysis (DB does start fine)

While trying to insert a row in any table expect KPI.KPI_MERGEIN, it is successful. But when a new row is inserted into KPI.KPI_MERGEIN table using command line tool it's throwing below error message (the same message that appeared in live

ij> INSERT INTO KPI.KPI_MERGEIN (A0_TXN_ID, A1_NE_ID, A2_CHU_IP_ADDR, A3_BATCH_DATE,A5_CODE) VALUES (-1, 'BMTDE', '192.2.1.3', 231456879, 'KSD');
ERROR 08006: A network protocol error was encountered and the connection has been terminated: the requested command encountered an unarchitected and implementation-specific condition for which there was no architected message

and in derby.log file it shows below error stacktrace.

Cleanup action completed

The problem is only with INSERT statement. When i try SELECT statement on KPI.KPI_MERGEIN table it is working well.The database file system size (in seg0) is 1.3 GB

Can anyone help me out in identifying the problem that why for one table alone its throwing the above error message ? Would upgrade to a new version help ?
