Subject Re: [firebird-support] Fatal lock manager error: invalid lock id (3527612) errorno:0
Author Dalton Calford
Hi Ann,

I am running with a standard configuration, and the time period between
such problems is averaging a month so a debug version on this database
system, would not be practical.

So, perhaps it is an issue with lock parametres. What setting would you
recommend for a database that has about 150 concurrent connections at
any one time with a average database size of 30 GB? The number of
tables, procedures and views is also on the order of about a thousand
objects or more......

I would like to think that it is a misconfigured server on my part vs a
problem with the lock manager itself.

best regards
