Error during connect to the instance Content Server MAXDB-XSERVER Receive

We rebooted this mornning a PROD Instance with SAPDB!

Second Instance is a Content Server. Now, we got an error during connect via

DBM Gui to Maxdb 7.6.06.04

2011-08-19 10:06:32 577 ERR 11926 XSERVER Receive packet, Ref:8 - socket recv error (110:Connection timed out

Environment variable : 1. Insctance PROD

2. Instance Prod Content Server

We couldnt connect to the database Instnce via DBMgui and also DB50 all collected data are visible, but its possible to start

DBACOCKPIT, analyse DB analyser : Message

Info Size of data cache 260306 pages, 99.98% in use, size of converter cache 1762 pages

Its seems so regarding to the Info of DB Analyser: Instance CSP (sap1) is up since 2011-06-10 12:20:10 that the Content server

didnt recognize that there was a boot this morning!!

In DBACOCKPIT it seems to be o.k. ! We could not boot the PROD Host asap again, because of the maintenance time window!

Where we could check more featur. of the content server. The processes seems to be o.k.!
