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

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,
