Hello

I am using Java with H2 to store serialized objects. Application stores 
many small data chunks (1kB) but it happens from time to time that data 
chuck size is quite large (20MB) - rarely but it happens. This is stored in 
table with int id and blob column for data. I am using H2 version 1.3.170 
(Maven repository) to start embedded database that uses file on disk.

I noticed that "trace.db" file appears couple of minutes after application 
start with message:
pageStore: Transaction log could not be truncated; size: 16 MB

When creating new H2 connection I always set auto commit to true. I also 
make sure to close statement after each insert and select using Java7 
autoclose mechanizm try(){}. Is there anything more I could do to avoid 
this warning. And another question is, does this affect any data stored in 
database?

Regards
M.Michalak
