9.21.FC6 - problems started with LSM installation in alpha tru64

Hi all! A customer with an Alpha running Tru64 Unix 5.1 installed new and larger disks mirrored with LSM (don't ask me why). Preliminary tests run ok but when users started to work this morning the JDBC sessions started to die with "System or internal error" and "Attempt to connect to database server (dbserver) failed". Also, sessions in dbaccess running complex queries frequently abort with error "25580 - System error occurred in network function". IDS logs show no problem. IBM/Informix support says can't find any problem. It's probably an OS problem derived from the activation of LSM but HP support is nothing like IBM/Informix's. Has anyone had a similar problem? TIA Fernando $ onstat -VInformix Dynamic Server 2000 Version 9.21.FC6 $ uname -aOSF1 alpha.iapmei.pt V5.1 1885 alpha -- Fernando Fernandez MoreData - Sistemas de Informa''o, Lda. http://www.moredata.pt sending to informix-list

Hi/Viva... The only change was on the disks? It doesn't sound like any disk related problem... Do the sessions connect through a firewall? It only happens with JDBC? Where is the application server? Nothing changed there? If you issue a netstat -a on the DB server do you see the same number of connections that you have on the application server? Regards/Cumprimentos. Fernando Nunes F.
