Hello,
Our MAXDB was running very fine in the last 8 Monthes till 2 weeks ago!
Our Java Application is having Problems (sometimes only) connecting to the DB!
in the logs:
SAP DBTech JDBC: Cannot connect to jdbc:sapdb://xxx.xx.xx.xx
/DB [Connection down, session released].
Java Application is running on its own Server and connect to the DB Server in the same DMZ
is it the Network?
thanks alot for your help
Please check the x_server logfile on the database server, you may have run out of connections.

Thanks Markus for your replay,
There are too many Errors in the:
/var/opt/sdb/data/wrk/xserver_"host".prt:
too many of:
2010-09-16 11:36:53 10472 ERR 11379 CONNECT Error getting TCP/IP host by address: 'xxx.xx.xx.xx.'
and some of such errors:
2010-09-16 11:40:15 4195 ERR 11308 IPC create_fifo: '/var/opt/sdb/data/ipc/us:DB/FIFO-4195.1' 0 666 mknod error, File exists

This means that the x_server is unable to resolve the name of the client that tries to connect, check your DNS configuration. If the resolver takes too long the connection may timeout and that's what you might see.

A pipe is trying to be created but the pipe exists already - and hence a connection can't be created.
