Build: NetBeans IDE 7.4 (Build 201310111528) VM: Java HotSpot(TM) 64-Bit Server VM, 23.21-b01, Java(TM) SE Runtime Environment, 1.7.0_21-b11 OS: Windows 7 User Comments: kwoodle: select * from db.table never returns when acting on db shown in Services Window. Returns when limit no of rows. Increased packet size from 4 MB to 10 MB GUEST: Background scanning... I really only have to turn NetBeans on to produce this error. I assume it has something to do with Action Items/CodeSniffer/MessDetectorbecause this error only occured after I set the scope for these items to package, and it started occuring after that. I have, however, set the scope back to file. This has had no effect on the occurance of the error.

Created attachment 146473 [details] stacktrace
caused by executing select * from some big database which returns huge amount of data (in one of the heap dumps there are ~2.1M results in one ArrayList)
*** Bug 243850 has been marked as a duplicate of this bug. ***
Comment 2 from Petr Cyhelsky points to most probable cause: To many rows are fetched by the JDBC driver. Closing as duplicate. *** This bug has been marked as a duplicate of bug 241142 ***
