MAXDB crashes sometimes

Hi,

several customers (about 4 of 50) report strange behaviour with MAXDB. The databse suddenly stops, the kernel error log reports a lot of things, which I'm not able to analyze. Can you help me?

In nearly all cases I simply restart the database and all seems to be fine, but I think there must be something wrong. What can I do?

Thank you, Christoph
