Getting IOPagingExceptions

[Mikael Jørgensen]

Hi,

We are using HawtDB together with a camel-aggregator.

This has been running flawless for a few months, but two weeks ago we
suddenly began getting:
org.fusesource.hawtdb.api.IOPagingException: Invalid extent read
request. The requested page was not an extent: xxxx

This was "fixed" by extending the buffersize from the default 8Mb to
32Mb, and resetting the hawtdb file.

Now the problem has arisen again and we have the same kind of
exceptions in the logs.

Is this exception due to HawtDB reaching its limit in buffersize?

If this is the case, the data that are persisted to HawtDB are not
very big in size, so it is unlikely that a single data set would cause
the HawtDB to go pass its limit.

Can it be that the HawtDB just grows?

We are currently running with hawtdb 1.5/hawtbuf 1.2 - we are able to
use hawtdb 1.6/hawtbuf 1.4 instead, but I do not know if this makes
any difference?

Best regards
Mikael
