Resource temporarily unavailable
If the installation fails with the following error message on the console:
fork() failed: Resource temporarily unavailable
The value of maximum number of processes allowed per user may not be large enough. This kernel attribute is a tunable and can be changed on any node of the cluster.
To determine the current value of "Maximum number of PROCESSES allowed per user", enter:
# lsattr -H -E -l sys0 -a maxuproc
To see the default value of this tunable and its valid range of values, enter:
# odmget -q "attribute=maxuproc" PdAt
If necessary, you can change the value of the tunable using the smitty interface:
# smitty chgsys
You can also directly change the CuAt class using the following command:
# chdev -l sys0 -a maxuproc=600
Increasing the value of the parameter takes effect immediately; otherwise the change takes effect after a reboot.
See the smitty and chdev manual pages.
