Problem during MAXDB backup

HEllo,

we have MAXDB 7.6.06.009 on Linux RHEL 4 . Backup (inrcemental and full) suddenly 😔 stopped working,

External backup log:

2010-08-03 10:00:18 The database has finished work on the request.

Receiving a reply from the database kernel.

Got the following reply from db-kernel:

SQL-Code :-903

and knldiag.err says:

2010-08-03 13:20:36 16158 ERR 11000 d0_aopen Error during creating semaphore, resource problem

2010-08-03 15:28:56 16186 ERR 3 Backup Data backup failed

Have you seen this? Do you have any recommendation for database or Linux parameters?

Thank you

    You have to increase the max file descriptors in /etc/sysctl.conf and you have to make sure the used shells for the user running the database software are adapted also.

    See

    http://www.cyberciti.biz/faq/linux-increase-the-maximum-number-of-open-files/

    and also check

    ulimit -a

    for the user running the database software.

      Hello,

      now I have other problem,

      ERR 51080 SYSERROR -9407 unexpected error

      ERR 3 Backup Data backup failed

      ERR 3 IOMan + An error occurred while accessing a volume,VOLUME_TYPE=data,VOLUME_ID=22,BLOCK_NO=1776647,NUMBER=2,ERRORTEXT=e

      ERR 3 IOMan + nd of file,NUMBER1=189

      ERR 6 KernelCo + Error in backup task occured, Error code 6433 "system_error"

      DB is running, no other errors, only during backup. Every backups has error in another data volume.
