Subject KahaDB failure with Active MQ 5.4 snapshot
Date Mon, 31 May 2010 09:27:54 GMT
Hello,

we have upgraded from 5.3.x series to a snapshot version because we
got several KahaDB errors. It was fine for a long time but then we
suddenly had an KahaDB error again. Any idea where is this coming
from? I assume its again something on creating index or such.

Thanks for any tips,
Christian
