Re: [h2] Moving from H2 1.3.176 to 1.4.187 results in sporadic ArrayIndexOutOfBoundsExceptions?
Hi Thomas, The default page size is 4096 bytes, did you set it manually to 2048 bytes? No, I didn't change it. Do note, that the databases were created with 1.3.176 and the crashes happened with 1.4.187. I've reverted to 1.3.176. That stopped the crashes almost immediately, although we are still getting a few. These newer crash messages refer to 4096 bytes. eg: Caused by: java.lang.ArrayIndexOutOfBoundsException: 4096 at org.h2.store.Data.writeVarInt(Data.java:1187) at org.h2.store.Data.writeValue(Data.java:531) at org.h2.index.PageBtreeIndex.writeRow(PageBtreeIndex.java:394) at org.h2.index.PageBtreeNode.writeData(PageBtreeNode.java:454) at org.h2.index.PageBtreeNode.write(PageBtreeNode.java:427) at org.h2.store.PageStore.writeBack(PageStore.java:1047) at org.h2.util.CacheLRU.removeOld(CacheLRU.java:216) at org.h2.util.CacheLRU.removeOldIfRequired(CacheLRU.java:142) at org.h2.util.CacheLRU.put(CacheLRU.java:116) On Saturday, 9 May 2015 02:12:07 UTC+10, Thomas Mueller wrote: Hi, I don't know what the problem could be.
