Question/Problem Description

Unable to start databases after increasing -B and -B2 parameter due to 1176 error.
Databases were originally running prior to increasing -B and -B2 parameters.
Able to reboot the machine and then was successful in starting some of the databases but not all of the databases due to 1176 error.

Steps to Reproduce

Clarifying Information

259 GB RAM on the machine.
200 GB allocated for progress project in the kernel.

project.max-shm-memory

privileged 200GB - deny -

system 16.0EB max deny

Data collected to analyze the issue: memstat, ipcs -ma, shmget.d, dtrace

Error Message	The data space of the process is not enough for the shm segment (1176)

Defect Number

Enhancement Number

Cause

Insufficient free memory available on the machine for the amount of shared memory being allocated to Progress.
Other non-Progress applications are running that are making use of RAM on this machine therefore not allowing Progress to
take advantage of the 200GB of shared memory allocated to it.

Example:

259GB RAM on the system.
200GB allocated in kernel for progress project.
More than 59GB being used by other non-Progress applications and programs which results in Progress not being
able to allocate 200GB of shared memory for the database due to memory constraints.

Resolution

Increase RAM.

or

Decrease -B and -B2 parameters so as not to exceed available physical free memory on this machine.
