SAP Note 18878 - No free storage of the class PERM is available

Symptom:

System crashes. The message appears in the syslog:
"No free storage of the class PERM is available."

Cause and prerequisites

The swap space configured in the operating system is not sufficient.
Cause can be:
1) R/3 is configured correctly and the swap space is too small.
You can get a rough approximation of the available swap space by using ipclimits. The line "Maximum Amount of Shared Memory Space" shows the quantity of swapspace that is currently free. This can be executed by stopping and restarting R/3.
UNIX command: ipclimits
2) Old processes or shared memory segments still exist which, due to an error, were not removed when the system last stopped. These can belong to either R/3 or the database. Display with: Command: ps -eafl (or other appropriate options)
Command: ipcs -ma
3) R/3 is configured incorrectly and therefore receives too much swap space. For example, the number of work processes is too high, the buffer is too large, the shared memory pool is too large. As of Release 2.1G, R/3 System profiles can be checked: Command: sappfpar pf= check

Solution
Determine the cause of the problem as described above and correct this, if possible.
Cause 1): Increase swap space size and restart computer
Cause 2): Delete old objects with 'kill' (processes) or 'ipcrm' (shared memories)
Cause 3): Correct the R/3 profiles, check with sappfpar and restart R/3.
UNIX command: ipclimits
