It is possible that the RFC failes due to the OS reching the limit on maximum number of processes.
First need to check the ulimit values on the OS system: For this you can refer KBA "2048826".
To do so in the command prompt type "ulimit -a" as shown below values must be appear in your system.
ulimit -a
time(seconds) unlimited
file(blocks) unlimited
data(kbytes) unlimited
stack(kbytes) 4194304
memory(kbytes) unlimited
coredump(blocks) unlimited
nofiles(descriptors) unlimited
threads(per process) unlimited
processes(per user) unlimited
Note:- For windows server the above check can resolve the issue. But for AIX system you need to follow the below steps to resolve.
On AIX there is a second limit for processes, which is set to 128 on your server:
[3]lsattr El
sys0 a
maxuproc
maxuproc 128 Maximum number of PROCESSES allowed per user True.
This maxuproc should be increased to atleasst 1024. See note 1972803 SAP on AIX:
Recommendations Section 3 for detailes:
"o Maximum number of processes for each user in the system:
This value (maxuproc) can be checked using the command 'lsattr El
sys0 a
maxuproc' and is often set too low at 128. You should use the
command 'chdev l
sys0 a
maxuproc=1024' to set the value to at least
1024."
Please increase the maxuproc to resolve this issue.
