Hi,

we have a problem acknowleging some alerts.


/var/log/xymon/hobbitd.log shows:

2010-03-29 23:23:04 Cookie 570429 not found, dropping ack


.bb 127.0.0.1 "hobbitdboard fields=hostname,color,cookie"

server10.internal.net|green|-1
server10.internal.net|red|947608
server10.internal.net|green|-1
server10.internal.net|green|-1

at the same time there is no problem acknowleging alert with cookie 947608
though.
could anyone give me some hints how to solve this problem?

p.s. we're running version 4.2.3
