Connection pool farmer error...

Toby, this is the first time I see this error with McKoi server:

[ TIME: Mon Feb 21 23:37:28 VET 2005 ]
% java.lang.NullPointerException
        at
java.util.AbstractCollection.remove(AbstractCollection.java(Compiled
Code))
        at

Code))

(
lvl: 40 )
  Connection Pool Farmer Error

I have increased some memory related values, because I have 2GB available:

**** Debug log started: Tue Feb 22 08:41:00 VET 2005 ****

% Starting Database Server

My environment:

* SuSE Linux Pro v9.0 kernel 2.4.21.266
* IBM JDK 1.4.2 SR1-1 (dec-2004)
* McKoi v1.0.3

I wonder if it may be caused by MaxPages=512 - it's the first time I
change this parameter from it's default. The server did run for about 7
days before triggering this exception, it forced a server restart.

Regards,
Martin
